North Seymour Island hosts the archipelago's largest frigate bird colonies and important nesting grounds for the famous blue-footed boobies. Visitors can witness the iconic mating dance where males show off their bright blue feet to attract females. The 90-minute walking trail winds through nesting habitats where birds sit just meters from the path. The island also features land iguanas, sea lions, and male frigate birds inflating their vivid red throat pouches.
