Destin is located on Florida’s Emerald Coast, which gets its name from its beautiful, clear green water. Beaches here have extremely fine, soft sand, so if you’re a beach-walker or your kids enjoy building sand castles, this could be a great destination for you.

It's no wonder Machu Picchu is Peru's most-visited site. Dating to the mid-1400s, it's a marvel of mortar-free limestone architecture perched on a high plateau deep in the Amazonian jungle. Get there via train from Cusco or, if you're not faint-hearted, make the trip on foot via a multi-day hiking trail—you'll travel through deep Andean gullies and enjoy stunning views.
