For those who cannot live without altitude Bonaire offers some spectacular cliffs to climb or to rappel down.
A bit easier is hiking/climbing Brandaris Hill (241 meters/784 feet) in the Washington Slagbaai park. This is the highest point on Bonaire, it offers a panoramic vista of the island. A footpath leads from the parking lot up the ridge.
The round-trip walk takes about 2 to 3 hours. Once at the top, you can see almost the entire island and also catch a glimpse of Curacao on the western horizon. On exceptionally clear days, even Venezuela is visible.
