The Los Tuneles or Cabo Rosa tour in Isabela island is the coolest snorkeling tour you can do in the archipelago and one of the best things to do in Isabela, Galápagos. You will see so much wildlife you won’t believe it.

We saw on the surface blue-footed boobies, penguins, sea lions, marine iguanas and orange crabs and underwater reef sharks, turtles, a sea horse, a sea lion, an eagle ray, a stingray, an octopus, a lobster, and beautiful schools of fish.

Apart from the wildlife, the lava structures underwater are mind-blowing, you can dive through infinite tunnels and caves, and to top it we saw like in Angelita’s cenote in Mexico, an hydrogen sulfide cloud. What an experience!
