North Seymour Island is a small, flat island with a land surface of approximately two square kilometres. It is a well known nesting site for frigatebirds and blue footed boobies. The island is also home to nearly 2,500 land iguanas.
The island was formed by a seismic event that caused a series of uplifts of submarine lava. Its origins as a seabed give the island its low, flat profile. It was named after the English nobleman, Lord Hugh Seymour.
North Seymour can be visited as a day tour from Santa Cruz. A trail loops around the island, through the largest colonies of frigatebirds in the Galápagos.
