Top Things to Do in Santa Cruz Galapagos Islands
Santa Cruz Island Galapagos is the most visited island in the archipelago and home to the only commercial airport with daily flights from Quito and Guayaquil. The best things to do in Santa Cruz Island Galapagos range from free beach walks at Tortuga Bay to $180+ day tours to neighboring islands like Bartolomé and North Seymour.
Santa Cruz Island is the heart of the Galapagos Islands and the main gateway for travelers. From iconic wildlife encounters to pristine beaches and nearby island tours, Santa Cruz offers endless experiences. Below are the 19 best things to do in Santa Cruz Galapagos Islands including location and how to get there.
1. Charles Darwin Research Station
The Charles Darwin Research Station is the most visited attraction in Santa Cruz Galapagos Islands. The center sits on the eastern edge of Puerto Ayora, a 15-20 minute walk from the main dock or a quick taxi ride. The complex houses the giant tortoise breeding program responsible for releasing over 7,000 tortoises back into the wild across the archipelago — including baby tortoises you can see up close in the nursery.
The most famous resident was Lonesome George, the last Pinta Island tortoise who died in 2012. His preserved body is now displayed in a temperature-controlled room, and modern breeding programs are working to genetically resurrect his species by crossing tortoises with high percentages of Pinta DNA. Beyond tortoises, you will see land and marine iguanas basking on the rocks and learn about Galapagos endemic flora.
Entry costs $10 per person and a local naturalist guide accompanies your visit (included). Plan 1.5-2 hours. After the center, walk down the iguana-strewn path to Playa de la Estacion and Playa Ratonera — two small free beaches great for snorkeling on calm days. You must show your Galapagos National Park ticket at the entrance. Not sure how to fit this into a trip? Send us your dates and we’ll map out the islands for you.
2. Giant Tortoises in the Highlands (El Chato / Rancho Primicias)
The Santa Cruz highlands are the only place in the Galapagos where you can walk among giant tortoises in their natural habitat. Three private reserves offer this experience: El Chato (the original and most documented), Rancho Primicias (right next door, very similar), and Rancho El Manzanillo (the quietest, sometimes with local dance performances). All three cost around $10 per person to enter and include rubber boots since the highlands are usually muddy.
Plan 2-3 hours at any of these reserves. The tortoises roam freely under scalesia trees and rest in mud pools — you walk between them on marked paths. Beyond tortoises, the highland forests are full of Darwin finches, short-eared owls, and the Galapagos flycatcher. El Chato also has three smaller lava tunnels (good if you are mildly claustrophobic), while Rancho Primicias has one almost-mile-long tunnel with no exit until the far end.
Reach the highlands by taxi from Puerto Ayora (about 45 minutes, $25-30 round trip with wait time) or join a half-day Highlands Tour from any agency in town for $40-50 per person including transport and lunch. Wear long pants, closed shoes, and bring a rain jacket — the highlands stay misty and cool even in dry season.
3. Los Gemelos Lava Sinkholes
Los Gemelos (The Twins) are two enormous volcanic sinkholes in the Santa Cruz highlands, formed when ancient lava tunnels collapsed thousands of years ago. They sit on either side of the road to Baltra airport, making them easy to visit on your way in or out of the island. Both craters are surrounded by one of the largest remaining scalesia forests in the Galapagos — endemic trees dripping with lichens and moss.
The real magic of Los Gemelos is the birdwatching. The scalesia forest is home to several species of Darwin finches, the Galapagos flycatcher, and short-eared owls hunting at dawn and dusk. Walking the short trails around each crater takes 30-45 minutes and reveals incredible views down into the volcanic chambers below.
Los Gemelos is free to visit and open during daylight hours. The best strategy: ask your airport taxi driver to stop here on the way from Baltra to Puerto Ayora ($5-10 extra). Combine with the lava tunnels and a tortoise reserve in a single highland circuit — most local operators run this as a half-day package for $35-45 per person.
4. Tortuga Bay Beach
Tortuga Bay is the most photographed beach in Santa Cruz Galapagos Islands and one of the few in the world rated in TripAdvisor’s top 25. The walk from Puerto Ayora takes 30-40 minutes along a paved cobblestone path through cactus forest, starting at the end of Charles Binford Street. There is a control point at the entrance where you sign in (no fee).
The beach has two distinct sides: Playa Brava (the first beach you reach) has strong waves and a powerful undertow — perfect for surfers and walking but NOT safe for swimming. Walk another 10 minutes to Playa Mansa, the protected lagoon at the far end, where calm clear water is ideal for swimming, snorkeling, and kayaking. Rent a kayak on site for $20/hour.
Wildlife you can expect: marine iguanas everywhere, sea turtles in the lagoon, white-tip reef sharks in the mangroves at high tide, and pelicans diving for fish. Bring everything you need — there are no restrooms, no food vendors, and no drinking water at Tortuga Bay. Best time: early morning (before 9am) when the crowds are gone or late afternoon when the light is golden. Avoid midday in dry season when the sand burns your feet.
A quick tip from our team: visiting Tortuga Bay Santa Cruz Galapagos is one of the few things to do in Santa Cruz Island Galapagos that is genuinely free and self-guided — no park ticket needed beyond your initial $200 Galapagos National Park entry fee. The control point at the trailhead closes at 5pm, so plan to be on the path back by 4:30pm.
5. Las Grietas
Las Grietas (The Cracks) is a narrow channel between two volcanic cliffs filled with crystal-clear water that is naturally filtered through mangroves before reaching the sea. The water is brackish (semi-fresh) and remarkably clean — you can see fish 20 feet below the surface when the sun is overhead. There are three connected pools in total, each progressively quieter; most visitors stay in the first one closest to the entrance.
Getting there from Puerto Ayora: take a $1.50 water taxi across the bay to Punta Estrada, then walk 10-15 minutes past Playa de los Alemanes and along a small salt-flat trail. The walk itself is a highlight, often with shorebirds and pink salt deposits.
Important 2025 update: Las Grietas now requires a registered guide for entry (you sign in at the kiosk and join a group). Entry is $10 per person and there is a 90-minute time limit per group. Best time to visit is noon when the sun is directly overhead and lights up the water, or early morning (7-8am) when you may have it almost to yourself. Avoid 10am and 5pm when cruise groups arrive.
Pro tip: combine Las Grietas with Tortuga Bay Santa Cruz Galapagos in a single day. Do Las Grietas in the morning (when the sun is high overhead and lights up the water), then walk back to Puerto Ayora and head straight to Tortuga Bay Santa Cruz for the afternoon. Both are free or low-cost and showcase the best free things to do in Santa Cruz Island Galapagos.
6. Puerto Ayora Town
Puerto Ayora is the largest town in the Galapagos and the base for most of your time on Santa Cruz Island. The 15,000-person town hugs Academy Bay with a lively waterfront (the malecon) running along the harbor. Walking the malecon at sunset is its own attraction: sea lions sleeping on the public benches, marine iguanas spitting salt water on the rocks, and pelicans diving for fish a few meters from the dock.
For food, head to Charles Binford Street (locally known as “Calle de los Kioscos” — the street of kiosks). After 6pm, a line of grills called Picalladas fire up serving fresh-caught fish, octopus, and the local specialty cazuela (seafood casserole in clay bowls). Most meals cost $10-15. Specific recommendations: Restaurante Sol y Mar for cazuela, 1835 Coffee Lab for the only 100% Galapagos-grown coffee on the island.
Practical info: there is one Banco Pichincha ATM at the main intersection (often runs out of cash on weekends, withdraw early). Hotels range from $20/night hostels to $250+/night boutique stays. Mid-range options like Sueños Silvestres or Hotel Mainao deliver hot water and reliable WiFi for $50-80/night. Cell coverage is patchy and internet is slow — plan accordingly.
7. Bartolomé Island Day Tour
The Bartolomé Island day tour is the most iconic and photographed Galapagos experience after Tortuga Bay. The 2-hour boat ride from Puerto Ayora takes you past Daphne Mayor (where you might spot blue-footed boobies and tropic birds) before reaching Bartolomé, a small volcanic island just east of Santiago.
On Bartolomé, you hike 372 wooden steps to the summit for the famous panoramic view of Pinnacle Rock — a dramatic volcanic spire rising from a turquoise bay. The hike is moderate (45 minutes round trip) and the viewpoint is one of the most recognized landscapes in the entire archipelago. After the hike, the boat moves to the beach at the base of Pinnacle Rock for snorkeling: Galapagos penguins (the only penguin species in the northern hemisphere), white-tip reef sharks, sea turtles, and tropical fish.
Cost: $180-220 per person depending on the operator, includes round-trip boat transfer, snorkel gear, lunch on board, and a naturalist guide. Tours leave around 6:30am and return by 4pm. Take seasickness medication 30 minutes before departure if you are sensitive — the open water crossing can get rough. Bring sun protection, water, and a hat. This is exactly the ground we cover on our Santa Cruz day tours.

Other Top Day Tours From Santa Cruz Galapagos
If your budget does not stretch to a boat-based day tour, the free alternative is to dedicate that day to Tortuga Bay Santa Cruz Galapagos plus a visit to the highlands — you get wildlife, beach, and giant tortoises for under $40 total instead of the $150-220 a day tour costs. Many local travelers split their week this way: 2-3 paid day tours + 2-3 free Santa Cruz Island Galapagos exploration days.
Beyond Bartolomé, Santa Cruz Galapagos is the launchpad for most day tours to neighboring islands. These are the four most popular options ranked by what most travelers book, with real 2026 prices.
North Seymour Island Day Tour
North Seymour Island is a 45-minute boat ride from Baltra and the top day tour for birdwatchers. The island is known for blue-footed boobies, magnificent frigatebirds (especially during mating season May-September when males puff up their red throat pouches), and orange land iguanas. Most tours combine the hike with snorkeling at Playa Las Bachas. Cost: around $180-200 with lunch included.
Santa Fe & South Plaza Combined Day Tour
This combo day trip covers two contrasting islands. Santa Fe has the largest sea lion colony in the Galapagos and the endemic yellow Santa Fe land iguana. South Plaza is tiny but spectacular with red Sesuvium carpetweed (June-January), nesting swallow-tailed gulls, and steep cliffs. Snorkeling at Carrion Point is included. Cost: around $190-210.
Floreana Island Day Trip
Floreana is the smallest inhabited island and feels frozen in time. The day tour includes Post Office Bay (a barrel where travelers leave postcards to be hand-delivered), the pirate caves at Asilo de la Paz, and snorkeling at La Loberia with sea lions and turtles. Long boat ride (2+ hours each way), so take seasickness medication. Cost: around $180-200.
Pinzon Island Snorkel Day Tour
Pinzon offers some of the best snorkeling near Santa Cruz Galapagos without going diving. The waters are home to white-tip reef sharks, sea turtles, and large schools of tropical fish. The tour usually includes a stop at La Fé beach for marine iguanas and starfish. Great for non-divers who want the wildlife experience. Cost: around $150-180.
8. The Santa Cruz Highlands Loop: Giant Tortoises, Lava Tunnels & Los Gemelos
Three of the best stops on this list — the giant tortoises at El Chato, Los Gemelos, and the lava tunnels — sit within a few kilometers of each other in the island’s misty interior. Locals don’t treat them as separate outings. The whole green belt is simply the highlands, and it feels like a different island up there: Scalesia forest, garúa drizzle, mud, and far more tortoises than people.
Most Santa Cruz Highlands Galapagos tours bundle all three into one half-day loop, and that’s exactly how I’d do it. Any white pickup taxi in Puerto Ayora will run the circuit and wait while you walk each site. Go early — the tortoises are more active before the sun burns through — and pack a light rain layer even in the dry season. The ranches lend rubber boots when the trails turn to soup. Trust the boots.
Full details on each stop are earlier in this guide: the tortoise ranches, Los Gemelos, and the lava tunnels.
9. Puerto Ayora Fish Market
The Puerto Ayora Fish Market is one of the most entertaining 30 minutes you will spend on Santa Cruz Island. Every morning, local fishermen and women clean and fillet the day’s catch on a stone counter facing the malecon, while their unofficial business partners — sea lions and pelicans — wait patiently below for scraps.
The market’s celebrity is Lupe, a female sea lion who has positioned herself directly behind the counter for years. She nuzzles the women filleting fish and gets first dibs on scraps. Around her you will see a chaos of pelicans fighting for fish heads, herons stealing from the pelicans, and occasionally a baby sea lion nursing on the steps.
The market operates Monday-Saturday from approximately 8am to 5pm (best wildlife activity 10am-2pm when most fish gets processed). Entry is free. If you want to buy fresh tuna or wahoo to cook yourself, prices range $3-6/pound — far cheaper than restaurants. Bring your camera but keep distance from the animals (touching wildlife is illegal in the Galapagos).
10. El Garrapatero Beach
Playa El Garrapatero is a quieter alternative to Tortuga Bay, located about 10km northeast of Puerto Ayora. The beach itself is a beautiful crescent of white sand with scattered volcanic rocks, much less crowded than Tortuga Bay and with predictable wildlife. Behind the beach sits a small brackish lagoon that is home to a resident colony of pink flamingos — bring binoculars.
On a calm day, swim out to the tidal pool offshore for some of the best snorkeling on Santa Cruz Island: sea turtles, marine iguanas (yes, they swim), white-tip reef sharks, and tropical fish. On the beach itself you will see Darwin finches in the bushes, sea lions and pelicans fishing, and the occasional ghost crab.
Getting there: rent a bike in Puerto Ayora ($20/day, $35 for e-bike — recommended for the hilly return) or take a taxi for $25-30 with wait. The walk from the parking area to the beach is a 15-minute trail through cactus forest — be careful of the highly toxic Manchineel trees (Hippomane mancinella) marked with red bands; never touch them or stand under them in rain. Bring everything; there are no facilities.
11. Scuba Diving at Gordon Rocks
Gordon Rocks is considered the single best scuba dive site accessible from Santa Cruz Island, and one of the top hammerhead shark spots in the whole Galapagos. The site is a sunken volcanic crater rim with three submerged pinnacles rising from 30 meters of water — strong currents bring in big pelagic species, including schooling hammerheads (May-November is best season), Galapagos sharks, eagle rays, manta rays, sea turtles, and king angelfish.
This is NOT a beginner dive. Gordon Rocks is rated for advanced divers only: strong currents, deep entry, and surface chop demand at least 30 logged dives. You will need an Advanced Open Water certification plus ideally Nitrox. Most operators require a check dive at a calmer spot like Punta Carrion before they take you here.
Cost: $180-220 per person for a 2-tank day trip, includes all gear, lunch, and PADI dive masters. Reputable operators on Santa Cruz: Scuba Iguana, Eagleray Tours, and Galapagos Sub-Aqua. Book at least 2-3 days in advance — only a limited number of permits are issued per day. If you are going to San Cristobal and want to dive Kicker Rock too, save Gordon Rocks for the end of your trip in case visibility is bad on a given day.
12. Lava Tunnels
The lava tunnels in the Santa Cruz highlands are one of the most surreal natural attractions on the island and a geological time capsule over 1 million years old. They formed when slow-moving lava on the surface cooled and hardened while faster-moving lava continued to flow underneath, leaving hollow tubes behind. The main tunnel is roughly 1 km long with a ceiling height of 6-10 meters, and you can still see the “wave” patterns of the original lava flow frozen into the walls.
Walking through is a slightly eerie experience: cool, dark, and silent except for your own footsteps. The largest tunnels are inside the Rancho Primicias and Rancho El Manzanillo reserves, while El Chato has three smaller ones that are easier if you are mildly claustrophobic. You enter through a collapsed section and walk straight through until you emerge into sunlight on the far end.
Practical tips: bring a flashlight (the tunnels are pitch black in the middle — phone flashlights work but charge to 100% first). Wear closed-toe shoes since the floor is uneven volcanic rock. Entry is included with the $10 reserve fee, so visit while you are seeing the giant tortoises. The lava tunnels typically take 20-30 minutes to walk through one way.
13. Santa Cruz Bay Tour
A Santa Cruz Bay Tour is a 3-4 hour boat trip around Academy Bay and the small islets just outside Puerto Ayora. The typical itinerary covers 4-5 stops: Punta Estrada beach, La Loberia (small islet with sea lions), Canal del Amor (mangrove channel), Las Tintoreras de Punta Estrada (white-tip reef sharks resting in shallow lava channels), and Playa de los Perros for a final snorkel.
What you will see: white-tip reef sharks (almost guaranteed at Las Tintoreras), marine iguanas, sea lions, blue-footed boobies on the cliffs, golden rays, and tropical fish during the snorkel stops. The pace is relaxed and the tour is suitable for non-swimmers — most snorkeling happens from the boat side with calm shallow water.
Cost: $60-80 per person depending on the operator, includes boat transport, snorkel gear, water, and a naturalist guide. Honest take from local operators: this tour is worth it if you have an extra half-day and want easy wildlife viewing without a long boat ride. If you are short on time, prioritize the Bartolomé or North Seymour day tours instead — they deliver more dramatic landscapes and rarer wildlife per dollar spent.
14. Playa de los Alemanes
Playa de los Alemanes (German Beach) is a small sheltered beach just past Punta Estrada, on the same path that leads to Las Grietas. The beach is named after a small German community that settled here in the early 1900s, and the calm shallow water makes it one of the safest spots near Puerto Ayora to swim with kids.
On the right side of the beach (looking at the water), small mangrove channels are a known hangout for white-tip reef sharks at high tide — bring a snorkel and you might see them in 1-2 meters of water. At low tide, the lagoon partially empties, exposing rock pools where you can find sea snakes, sally-lightfoot crabs, and small tropical fish. There is no sand left at high tide, so check the tide schedule before going.
Getting there: $1.50 water taxi from Puerto Ayora dock to Punta Estrada, then a 5-minute walk along the boardwalk past Finch Bay Hotel. You can rent kayaks from Finch Bay reception ($20/hour). Combine with Las Grietas in the same morning for the most efficient half-day. Entry is free.
15. Laguna Las Ninfas
Laguna Las Ninfas is a peaceful mangrove lagoon just one block from the malecon in Puerto Ayora, easy to reach on foot in 5 minutes. The boardwalk loops around clear shallow water where you can spot green sea turtles, golden rays, and small fish without paying anything. It is one of the most relaxing free things to do in Santa Cruz Galapagos Islands and a perfect break between busier activities.
16. Cerro Mesa Ecological Reserve
Cerro Mesa is a private reserve about 30 minutes from Puerto Ayora on the way to Playa El Garrapatero. It is the quieter alternative to El Chato for seeing giant tortoises in their natural habitat, plus you get a moderate hike to a viewpoint with panoramic views over Santa Cruz Island. Entry is around $5, much cheaper than the main reserves, and you will often have the trails completely to yourself.
17. El Trapiche Coffee Tour & 1835 Coffee Lab
For a break from wildlife, visit El Trapiche Ecologico Galapagos on the way to Playa Garrapatero. Senor Cabrera shows you how sugar cane is extracted, distilled, and how coffee beans are roasted the old-fashioned way, with chocolate tastings included. Back in Puerto Ayora, 1835 Coffee Lab serves 100 percent Santa Cruz Galapagos grown coffee roasted in-house — a must for serious coffee drinkers.
18. Playa Las Bachas
Playa Las Bachas is a turquoise-water beach on the north coast of Santa Cruz Island, named after two abandoned US Navy barges from World War II that you can still see half-buried in the sand. The flat clear water is great for swimming with marine iguanas, sea lions, and reef sharks. Walk to the lagoon behind the beach to spot pink flamingos. Usually reached as part of a day tour combined with North Seymour.
19. Cerro Dragon (Dragon Hill)
Cerro Dragon, on the northwest coast of Santa Cruz Island, is famous for its colony of land iguanas — bright yellow-orange and only found in a handful of spots in the Galapagos. The short trail loops past a flamingo lagoon and ends at panoramic views of nearby islands. This is a tour-only site (no independent visits allowed) and is commonly added to bay tours from Puerto Ayora.
