Aruba's wildly sculpted landscape is replete with rocky deserts, cactus clusters, secluded coves, blue vistas, and the trademark divi-divi tree. To see the island's wild, untamed beauty, you can rent a car, take a sightseeing tour, or hire a cab for $45 an hour (for up to four people). The main highways are well paved, but on the windward side (the north- and east-facing side) some roads are still a mixture of compacted dirt and stones. Although a car is fine, a four-wheel-drive vehicle will allow you to explore the unpaved interior.
Traffic is sparse, but signs leading to sights are often small and hand-lettered (this is slowly changing as the government puts up official road signs), so watch closely. Route 1A travels southbound along the western coast, and 1B is simply northbound along the same road. If you lose your way, just look to the divi-divi trees, which always lean southwest.
