Geo-nerds will love the island of Aruba for its natural rock formations. It also makes for some pretty amazing views for an island that is otherwise pretty darn flat. One of the largest natural rock formations is Casibari. To get to these gigantic tonalite boulders, you’ll need to navigate to a quiet residential area, just off the main road in Santa Cruz. It’s an easy diversion as part of a day trip, and the cacti-lined trails and steps lead you to some breathtaking 360-degree views of the island.
