When you think Bonaire, you think diving. So what’s to do topside? While you’re decompressing, sign up with Outdoor Bonaire to go caving in the island’s eerie recesses. The outfitter also leads nature hikes under the full moon, cross-island bike rides, and, coming as soon as the permits arrive, rappelling down a 19th-century lighthouse. 011-599-791-6272, www.outdoorbonaire.com
