It is an experience that weaves together the thrill of discovery with the calm of a pristine underwater world, accessible mainly through specialized tours departing from Puerto Villamil.
The uniqueness of its formations and the incredible concentration of wildlife make it, without a doubt, one of the top attractions on any trip to the Galápagos.

Fun Facts about Los Túneles#
Unique Geological History and Formation
Los Túneles came to be millions of years ago, forged by a geological process. When volcanic lava spilled into the ocean, it cooled in a flash, sculpting unique features: tunnels, caves, and submerged rock formations. These structures are more than eye-candy; they also provide refuge and habitat for countless marine and terrestrial species.
Biodiversity and Featured Wildlife
This destination is considered a marine sanctuary thanks to its remarkable biodiversity and the strict protection enforced by the Parque Nacional Galápagos (Galápagos National Park). The intricate network of tunnels, caves, and shallow waters creates an ideal micro-habitat that offers shelter as well as prime feeding and breeding areas for an incredible variety of marine life. It is one of the few places on Earth where, if weather and sea conditions allow, you can swim side by side with sea turtles, white-tip reef sharks, giant manta rays, and seahorses, while also observing penguins and blue-footed boobies up close in their natural environment.
How to Visit Los Túneles?#
Reaching Los Túneles is an adventure in its own right and calls for some planning, since this is a spot you can’t visit independently. We’ll tell you everything you need to know below:
Day Trip from Puerto Villamil
You can visit Los Túneles in just one day. On this adventure, you sail through breathtaking scenery and pause at tiny islotes to watch birds. After about forty-five minutes on the water, you will reach the famous tunnels, where you walk over the rock formations and spot different animal species as you stroll and take in the landscape. Later, you can go snorkeling, and to cap it all off you will savor a delicious meal on board the boat.
The only way to reach Los Túneles is on a guided tour authorized by the Galápagos National Park. These tours are run by travel agencies in Puerto Villamil. Typically, there are two departure times: one early in the morning and another around midday.
