Dive Site Overview

Exploring Bartolomé/Cousin Rocks unfolds as a day of two distinct dives, each offering a window into the rich Galápagos underwater world. Dives here generally range from 18 to 25 m (59-82 ft) in depth, allowing ample time to explore the diverse topography, with maximum bottom times typically an hour per dive, depending on air consumption and no-decompression limits.

Moving along these vibrant walls, divers can observe the intricate ecosystems thriving in the deeper blue. After a surface interval that might include observing penguins on the nearby shores, offering a chance to decompress and enjoy the scenery, the second dive usually focuses on the reef and the shallower platform.

This platform, at around 10 m (33 ft), often reveals a bustling cleaning station, providing intimate encounters with reef inhabitants. This site is characterized as a rewarding blend of reef and wall diving, with a sandy bottom also present in certain areas, making for varied underwater scenery and opportunities for encounters with an array of invertebrates and numerous reef fishes, ensuring a dynamic and memorable diving itinerary.
