Genovesa Island occupies about 14 km2 and its maximum elevation is 64 m. The horseshoe-shaped island has a volcanic caldera whose wall has collapsed, forming the large Darwin Bay, surrounded by cliffs. Arcturus Lagoon, located in the center, is filled with salt water and its crater sediments are less than 6,000 years old.
Although there are no known historical eruptions of Genovesa, there are relatively young lava flows on the slopes of the volcano. This outlying island is located in the northeastern part of the archipelago. Many cruise ships are unable to include it due to the long distance to reach it, which takes about 8 hours.
Darwin Bay, on the south coast, is almost landlocked and surrounded by high cliffs. The water is teeming with microscopic marine life, which is why many associate it with green pea soup. The beach at Darwin Bay is coral, where a 750-meter trail leads to seabird colonies. There is also the option of taking a panga (boat), during which you are usually accompanied by sea lions. Here you will be able to observe the cliffs from the sea side, which are home to large
El Barranco is an extraordinarily steep trail that takes you past a colony of vibrant seabirds to 25 m high cliffs. At the end of the trail, continue inland and pass other seabird colonies in a Palo Santo (Bursa tree) forest. Upon exiting the forest, one encounters a rocky plain, where at the cliff edge are masked and red-footed boobies, wonderful frigate birds, swallow-tailed gulls, red-billed tropicbirds and hundreds of Galapagos swallows. Galapagos Swallows are unlike any other in the world because they fly all day to avoid predators and return to their hollow nests at night. Genovesa also offers excellent snorkeling opportunities, although the water is a bit murky due to the proximity to the beach and the view of the cliffs is better. Thanks to its rich food supply, the bay is often teeming with marine iguanas and is also frequented by juvenile hammerhead sharks.
When crossing the equator, many cruise ships offer an "equator baptism" to passengers who have never crossed the equator at sea.
