Genovesa Island, located in the northeastern part of the Galápagos archipelago, is a remote island often referred to as “Bird Island” due to its significant seabird colonies. Shaped by a large volcanic caldera, much of the island consists of steep cliffs that enclose a bay known as Darwin Bay. Covering approximately 14 square kilometers, it is relatively small compared to other islands but is notable for its abundance of birdlife and distinctive geological features.
The island’s volcanic origins are visible in its horseshoe-shaped crater and eroded lava formations. The bay, formed by a partially collapsed caldera, provides a sheltered anchorage for visiting vessels. Vegetation on Genovesa is limited but includes saltbush, mangroves, and prickly pear cactus, which provide important habitats for nesting birds.
Darwin Bay is the main landing site and is accessible via a white coral beach. A trail leads through mangroves and saltbush thickets, where large colonies of red-footed boobies, great frigatebirds, and swallow-tailed gulls can be observed. The red-footed booby is particularly abundant on Genovesa, with one of the world’s largest populations. Frigatebirds are often seen displaying their inflated red throat pouches during mating season, while the swallow-tailed gull, the only nocturnal gull species, nests along the cliffs. Other species include Nazca boobies, lava gulls, and storm petrels. Short-eared owls, adapted to hunt petrels, are also found on the island.
Another visitor site, Prince Philip’s Steps (El Barranco), is located on the southern cliffs. A steep path ascends from the landing point to the top of the plateau, offering access to lava fields and sparse vegetation where additional seabird colonies can be seen. This area provides an opportunity to observe the island’s large populations of storm petrels and their predators, the short-eared owls. The cliffs themselves are home to nesting seabirds and offer expansive views of the bay.
Snorkeling is also possible in Darwin Bay, where marine life includes tropical fish, rays, and occasional sharks. Access to Genovesa is strictly regulated, and only guided tours are permitted under the supervision of the Galápagos National Park.
Genovesa Island combines geological interest with unparalleled opportunities for bird observation, making it a key destination for understanding the ecological diversity of the Galápagos.
