This small, arid boomerang of an island is a divers' paradise. Skeptical? Read the license plate on your rental car, pal. Bonaire really does have some of the best diving in the region, most of it within the Marine Park encircling its shore.
The average daily high stays around 28°C (82°F) all year, and humidity is tolerable, so the best time to go is the low season of May to mid-December when rates come down. Bonaire is out of the hurricane belt so you don't have to figure the big blow into your schedule.
Although the flamingo sanctuary is off-limits to tourists, lucky visitors with a strong pair of binoculars can witness the comings and goings of Bonaire's most beloved guests. For other flamingo-viewing spots, head to the Willemstoren lighthouse at the southern tip of the island.
