The best-known walking route heads up to a restored 14th-century castle, a fortress once used to keep pirates off the island.The 30-minute walk to the castle meanders along the northern side of the island before taking you to the 80m-high bluff where the castle looms.
Guides also sometimes lead the 20-minute walk to Es Celler, a farmhouse-turned museum once home to the Feliu family, which owned the entire island in the early 20th century. Nearby stands a monument to the French prisoners who died on Cabrera.
Other possible routes lead to the N’Ensiola lighthouse (four hours, permission required), the southern sierra of Serra de Ses Figueres (2½ hours, permission required), or the highest point of the island, the 172m Picamosques (three hours, permission required).
The island is a wonderful place for snorkelling. While you need special permission to dive here, you can snorkel off the beach. Or, in July and August, sign up for the guided snorkelling excursions offered by park rangers.
This is prime territory for birdwatching: marine birds, birds of prey and migrating birds all call Cabrera home at least part of the year. Common species include the fisher eagle, the endangered Balearic shearwater, Audouin’s gull, Cory’s shearwater, shags, ospreys, Eleonora’s falcon and peregrine falcons.
Terrestrial wildlife is also abundant. The small Balearic lizard is the best-known species on Cabrera. It has few enemies on the archipelago and 80% of the species population lives on Cabrera.
