There is no permanent population, but there might be at any given time just under 100 National Park staff members and other personnel on the islands.

Cabrera Archipelago National Park is a restricted cruising destination, and boats may not anchor in the island's natural harbour, but must use laid moorings which have tot be booked in advance.

Many species survive on Cabrera that are rare in other parts of the Balearics, such as sea snails and the very unusual black lizard[clarification needed].

Various types of cetaceans[4] such as sperm, pilot, dolphins,[5] and fin whales[6][7] are regular and others such as humpback and orca on occasions,[8][9] and loggerhead turtles[10] can be found.

Hiking possibilities are abundant generally on organised tours, although both the castle and the lighthouse can be accessed unsupervised.
