This National Park covers almost 20% of Aruba, mostly its rugged and dry interior. The best way to explore the divi divi trees, aloe and iguanas that populate the park, is on foot from a well-worn hiking trail. The park is always open, and there is a good lunch cafe on the northeast coast.
For a bit of soft-adventure spelunking, head to the Guadirikiri Caves. Often filled with harmless bats, the caves’ eerie sunlight patterns and pirates’ lair history help visitors get in touch with their swashbuckling side. It’s recommended you bring a flashlight; if you can’t bring one they are available for hire at the entrance to the caves.
