Washington-Slagbaai protects Bonaire's wild northwest: cactus forest, limestone coast, salt lakes, beaches, and Brandaris, the island's 241-metre high point. Unpaved one-way driving routes lead through the park, with stops for viewpoints, short walks, swimming, and snorkelling. The road is slow and rough enough that even the shorter circuit takes a substantial part of the day.
Wildlife includes flamingos, iguanas, and the yellow-shouldered Amazon parrot, while Wayaka and Slagbaai Bay offer clear-water stops when conditions cooperate. Brandaris is a hot, exposed climb and requires an early start within park rules.
Entry and last-admission times are enforced so visitors can leave before the gate closes. Check the current vehicle requirements, arrive early, carry food and ample water, and make sure your rental agreement permits park driving. A nature-fee receipt is required under the current system.
