Camping is permitted in the forest reserves; you usually have to get a permit in advance although often they are available at the sites themselves. Camping is also allowed on some of the public beaches. Government agencies expect everyone to arrive or call before 1500. You can take públicos to some of the camping places, but with difficulty, car rental is advised.
