The Northern Scenic Route takes you into the heart of Bonaire's natural wonders—desert gardens of towering cacti (kadushi, used to prepare soup, and the thornier yatu, used to build cactus fencing), tiny coastal coves, and plenty of fantastic panoramas. The road also weaves between eroded pink-and-black limestone walls and eerie rock formations with fanciful names such as the Devil's Mouth and Iguana Head (you'll need a vivid imagination and sharp eye to recognize them). Brazil trees growing along the route were used by Indians to make dye (pressed from a red ring in the trunk). Inscriptions still visible in several island caves were made with this dye.
A snappy excursion with the requisite photo stops will take about 2½ hours, but if you pack your swimsuit and a hefty picnic basket (forget about finding fast food), you could spend the entire day exploring this northern sector. Head out from Kralendijk on Kaya Gobernador N. Debrot until it turns into the Northern Scenic Route. Once you pass the Radio Nederland towers, you cannot turn back to Kralendijk. The narrow road becomes one way until you get to Landhuis Karpata, and you have to follow the cross-island road to Rincon and return via the main road through the center of the island.
