After you've explored the island's underwater life, dry off and direct your attention to the Donkey Sanctuary Bonaire. Established in 1993 by Dutch Nationals Marina Melis and her husband Ed Koopman, the sanctuary provides a safe and peaceful oasis for more than 400 orphaned donkeys.

The donkeys are very friendly (recent travelers compared them to cute, oversized dogs), and they aren't afraid to interact with you. The sanctuary also sells bags of food you can feed to the animals—another sure-fire way to earn some donkey affection. One TripAdvisor user says, "We heard during our last trip that the donkey sanctuary was fun... I would give up several dives just to go again."

The sanctuary welcomes visitors daily from 10 a.m. to 5 p.m., and you can tour the sanctuary on foot or by car or bike. Admission for adults costs $7, while admission for children 12 and under is $3.50. The Donkey Sanctuary Bonaire is south of Kralendijik, five minutes from Bonaire International Airport.
