Genovesa, also known as Tower Island, is located in the northeastern realm of the archipelago. The National Geographic Endeavour II was anchored inside the caldera for the entire day, in a bay known as Darwin Bay.

We explored two different sites, Darwin Bay and Prince Phillip steps, and at both sites we got a chance to see large colonies of sea birds, such as great frigatebirds, Nazca boobies, red-footed boobies, and swallow-tailed gulls.
