The nature reserve Arikok covers close to one-fifth of Aruba and contains virtually all the flora and fauna that the country has to offer — against a background of beautiful volcanic rock formations. In addition, the national park is home to a large number of historical heritage sites.
On this part of the island, the first thing that catches the eye are the jagged hills, the remains of old lava flows. The 34-square-kilometre park also holds numerous types of other rocks — including chalk stone, fossilised coral and jagged igneous rocks with green quartz — and is home to the 2 tallest hills on the island: the Jamanota (188 metres) and the Arikok (176 metres), after which the park was named.
