North of Baltra (South Seymour) is the small islet of North Seymour. The two islands are very similar in appearance both created from Geological Uplift and having typical arid vegetation including Prickly Pear Cacti, Palo Santos Trees and Salt Bushes. The visitor trail on North Seymour is approximately (2 km) in length crossing the inland of the island and exploring the rocky coast. Along the way the trail passes colonies of Blue-Footed Boobies and Magnificent Frigatebirds.
