Sullivan Bay
Sullivan Bay, on the eastern coast of Santiago Island, is one of the most spectacular and beautiful visitor sites in the Galápagos. Its lava flow was formed during an eruption in 1897 and is extremely young in geological terms. The lava is so fresh and remarkably well preserved that in places it looks as though the eruption has only just happened. From Santa Cruz, Sullivan Bay is normally visited on the same day tour as Bartolomé.
Why visit?
This is, quite simply, the finest lava flow to visit in the Galápagos and a must-see for anyone interested in the islands’ volcanic origins. The trail crosses a breathtaking landscape of smooth, folded pāhoehoe lava, extraordinary rope-like patterns, lava bubbles and rougher, broken formations. There is an enormous amount to see and learn here about how lava flows, cools and creates new land.
The dark, almost untouched lava contrasts beautifully with the small white coral beach beside it. Marine and intertidal life along the boundary between the lava and the sea also adds interest, but the outstanding attraction is the lava flow itself: its freshness, its beauty and the spectacular variety of formations preserved across its surface. A coastal snorkel may also be included, depending on the authorised itinerary and sea conditions.
What to consider
The lava field is exposed, hot and without shade. Visitors should wear secure footwear and take care on uneven and sometimes sharp volcanic surfaces. The landing and precise activities depend on National Park arrangements, the vessel’s authorised itinerary and sea conditions.
Sullivan Bay is particularly rewarding for travellers interested in geology, volcanism and the early stages of ecological colonisation. Wildlife is generally less concentrated than at sites such as North Seymour, so its principal attraction is the landscape and the story recorded in the lava.
