Aruban rattlesnakes, parakeets and whiptail lizards make their home in the Arikok National Park, as do numerous iguanas, goats, donkeys and migratory birds. So, if you don't like animals, stay clear of Aruba's southeastern quadrant, which is dominated by this ecological preserve and extremely popular tourist stop.

Many who visit Arikok make a day of observing the area's wildlife, exploring the caves, sand dunes and limestone cliffs that populate the area, or cooling off in the natural pool that sit within the park's limits. Many choose to drive through the park in a four-wheel-drive vehicle (in fact, some attractions can only be reached by a four-wheel drive vehicle), but you can also get out and hike in some spots. Considering the breadth of land and activity in Arikok, it's best to pick one or two top things to do or perhaps visit the park again on another day. Recent visitors said it's a must-see attraction and like nothing else on Aruba.

Admission to Arikok National Park costs $11. Children ages 17 and younger can enter for free. The park is open daily from 8 a.m. to 4 p.m. Stop by the visitor center to speak with a ranger and pick up a map. Visit the park's official website for more information on hours, park rules and fees.
