Covering the northwest portion of the island and comprising almost 20% of the land, Washington-Slagbaai National Park is a great place to explore. Roads are rough and all-but-impassable after a rain, but are well worth the effort. The terrain is mostly tropical desert, and there is a proliferation of cacti and birds. Entrance is about 5km (3mi) from Rincon.
Look for flamingos in the lowlands and parrots perched on shrubs near Pos di Mangel. Large bright green iguanas are just one of the many reptile species you might spot. You'll also see lingering evidence of the aloe plantation and goat ranch that used to be here - don't run over any wild descendants of the latter.
