Arikok National Park covers about 7,900 acres on the rugged eastern third of Aruba, the wild counterpart to the resort side of the island. It was officially established in 2000 to protect its biodiversity, its geological formations and its history.

A visit is a day outdoors. Trails run over hills and through caves to wild beaches and natural pools on the east coast, and most are clearly marked. Plan for heat and carry water, since the landscape offers little shade.

• There is almost no shade and the sun is brutal by mid-morning, so arriving at opening is advised. Bring plenty of water and a good hat.
• Park guides must be booked in advance. A guide can accompany hikers, and organized tours are usually led by park rangers.
• The park is open daily except January 1, and entry gates stop admitting visitors in the late afternoon.
• UTVs and ATVs are banned in the park. The conservation pass can be bought online ahead or at the San Fuego visitor center.
