Bonaire
It’s one of the best ways to stay cool in the Caribbean summer — by staying underwater. This is the great diving destination in the Caribbean, but you won’t lack for options when you climb back ashore — from a remarkably diverse culinary scene to great shopping in the capital, Kralendijk. For a luxury stay, it’s the Harbour Village; for an all-inclusive stay, try the Plaza resort; for budget-friendly option, go for the Caribbean Club.
