What are Los Túneles in Isabela, Galapagos?

Carved by lava and shaped by the sea, Los Túneles in Isabela, Galapagos offer one of the most extraordinary underwater landscapes in the archipelago. This otherworldly site combines geological wonder with rich marine life, making it a must-visit stop for nature lovers and snorkeling enthusiasts alike.

A surreal lava landscape beneath the sea

Los Túneles, also known as Cabo Rosa Tunnels, are a network of lava formations that were created when molten lava met the ocean and solidified, leaving behind a maze of arches, bridges, and underwater passages. Over time, the sea carved out pools and tunnels, creating one of the most visually stunning and ecologically rich snorkeling spots in the Galapagos.

Beneath the calm, shallow waters, you’ll discover an alien-like landscape where vibrant marine life thrives. It’s not just a tour—it’s like stepping into another world, with the added magic of swimming alongside reef sharks, sea turtles, rays, and even seahorses.

Where are the Cabo Rosa Tunnels located?

Los Túneles are located off the southern coast of Isabela Island, the largest island in the Galapagos archipelago. The site is accessible only by boat from Puerto Villamil, and it typically takes about 45 minutes of navigation to reach this hidden gem.

Its remote location keeps it pristine and less crowded, making it a favorite among photographers, nature lovers, and snorkelers looking for a peaceful, awe-inspiring encounter with the Galapagos marine ecosystem.

Tour highlights: what to expect at Los Túneles Galapagos

From the moment your boat reaches the volcanic coastline of Isabela, you’ll realize that Los Túneles Galapagos tour is unlike any other. Here’s what makes this experience truly unforgettable:

Snorkel through lava-formed tunnels and arches

Cabo Rosa’s unique lava formations have created an underwater labyrinth of arches, tunnels, and pools. As you snorkel through these surreal structures, you’ll feel like you’re floating through another planet—one sculpted by fire and cooled by the ocean.

Swim alongside sea turtles, reef sharks and rays

The shallow, crystal-clear waters of Los Túneles Isabela Galapagos are home to an incredible variety of marine life. Swim peacefully among green sea turtles, white-tip reef sharks, eagle rays, and even seahorses hiding among the coral.

Relax on pristine bays and hidden lagoons

Between snorkeling sessions, unwind on small sandy coves and calm lagoons only accessible by boat. These quiet moments allow you to take in the serenity of Isabela Island’s untouched beauty—where volcanic terrain meets turquoise water.

    Amazing, smooth experience -- flexible itinerary  - I actually did this trip back in November 2019 and never got around to writing this much-deserved review. Now that I have this Tripadvisor account up and running, I wanted... read more to say that this was a truly unforgettable trip, and the flexibility that this company gave (through my contact Christian) by allowing me to make my own one-week itinerary definitely played a big part in making it a spectacular experience. I basically sent the itinerary I wanted to three tour companies, and by far, this company gave me the best deal, which made it a no-brainer. Really saved me a lot of headaches in planning the logistics.

    Usually they say "you get what you pay for" -- in this case, it was great value for money. Went scuba diving, kayaking, hiking on a volcano, snorkeling with sharks and seahorses, touring the Charles Darwin facilities on two islands, etc. etc. and basically saw ALL the animals that I had on my wish list. Truly amazing. They provided the most affordable option, and yet the hotels and tour services that we received were top-notch, for one all-in price (which even included some meals). No problems at all in coordination even though we landed on one island, went from one island to another by commuter speedboat, and flew out from another island. Someone was always there to take us to the next activity. Even during the trip itself, they were very flexible and accommodating of our needs. The service provided exceeded my expectations! Highly recommend this company and hope they are flourishing despite the shock that COVID brought 🙏
