North Seymour Island is a small island in the Galápagos Archipelago, located just north of Baltra Island. It has an area of approximately 1.9 square kilometres and reaches a maximum elevation of about 28 metres. The island was formed by seismic uplift rather than volcanic activity, resulting in its flat terrain covered with low vegetation.
One of the principal attractions on North Seymour is its large colony of magnificent frigatebirds. The island is one of the best places in the Galápagos to observe their courtship displays. During the breeding season, males inflate their red gular sacs to attract females, creating a distinctive visual spectacle. The island is also home to great frigatebirds, allowing visitors to compare the two species in close proximity.
Blue-footed boobies nest extensively on North Seymour. Visitors can observe their courtship rituals, which include dancing and showing their brightly coloured feet. The nests are located close to the walking trails, providing unobstructed views of their behaviour and chicks during the breeding season.
The island’s coastal areas are frequented by Galápagos sea lions, which rest on the rocky shores and beaches. Marine iguanas are also present, often seen basking on rocks near the coastline. The vegetation consists mainly of palo santo trees, prickly pear cacti, and saltbush, providing a dry and open landscape that supports easy wildlife viewing.
A circular trail of approximately two kilometres leads visitors through the interior and along the coast. Along this trail, land iguanas can be observed feeding on cactus pads and other vegetation. These iguanas were introduced to North Seymour from Baltra in the 1930s as part of a conservation programme.
North Seymour Island does not have any permanent human settlements and is visited only by guided tours. Its close proximity to Baltra makes it a common destination for day trips. The island is valued for its high concentration of wildlife within a small area, allowing visitors to observe numerous iconic Galápagos species within a single short visit, including seabirds, land iguanas, marine iguanas, and sea lions.
