Genovesa Island is a shield volcano in the Galapagos Islands in the eastern Pacific Ocean. The island occupies about , and its maximum elevation is . The horse-shoe shaped island has a volcanic caldera whose wall has collapsed, forming the Great Darwin Bay, surrounded by cliffs. Lake Arcturus, filled with salt water, lies in the centre, and sediment within this crater lake is less than 6,000 years old. Although no historical eruptions are known from Genovesa, there are very young lava flows on the flanks of the volcano.
This island is known as Bird Island, because of the large and varied bird colonies which nest here. There are an abundance of frigatebirds and it is the best place to see red-footed boobies, masked boobies, swallow-tailed gulls, storm petrels, tropical birds, finches, and mockingbirds.
Prince Philips Steps is an extraordinary steep path that leads through a seabird colony full of life, up to cliffs that are 25m high. At the top, the trail continues inland, passing more seabird colonies in a thin palo santo forest. Leaving the forest, you can overview a rocky plain. The storm petrels here are different from any others in the world because they fly around during daytime. To avoid predators, they only return to their nest holes at night.
The smallest Marine Iguana in the archipelago lives here.
In Darwin Bay there is the possibility to either dive along the inner wall or go to the outer wall, which is less protected. Another possibility is to dive from the outside of the volcano through the channel into the caldera.
