Snorkelling in Sullivan Bay

Snorkelling in Sullivan Bay


Galápagos visitors are sometimes a bit anxious about snorkelling here. Many people are familiar with shallow and warm Caribbean waters, but in the Galápagos, it can be more challenging, with deeper water, mild currents, thermoclines, and cooler temperatures. But once you enter the water, be ready for a scene right out of a children’s animated film reminiscent of “Finding Nemo”. One of the best locations is Sullivan Bay.


Flanked by sandy beaches and swirls of lava, the beach features some of the most fabulous Galápagos wildlife, including sea lions, penguins, and sea turtles. But it’s also home to a plethora of aquatic creatures, including starfish and huge schools of yellow-tailed surgeonfish.

As its name indicates, these grey-striped fish have an almost electrically-bright yellow tail fin. These completely herbivorous fish feed in schools, and it’s common to see them eating algae attached to rocks and coral.

The species is distributed from Costa Rica to the Galápagos on Latin America’s Pacific Coast. They can be found at a depth of up to 30 metres, but usually they are found between three and 25 metres. While they can grow to a maximum size of 60 centimetres, on average they measure 25 centimetres. What it’s like to swim among them is almost impossible to describe!
