San Andrés at $351 RT

When it comes to beachy backdrops in the Caribbean, Dulles definitely delivers. 

But instead of swiping up dime-a-dozen flights to the Dominican, why not change direction? Where to? Well, to a little archipelago off the Caribbean coast of Nicaragua! 

It might be underappreciated by American travelers (it's practically impossible to find cheap flights), but San Andrés is Colombia's favorite vacay spot. Can't fault 'em, I mean, look at this view! 

But before you plant your bare feet on one of its gorge beaches and call it a day, allow me to point you towards the ferry port…

The journey to the idyllic island of Providencia is an experience in and of itself, a three-hour catamaran with complimentary sea-sick pills and bags.

Be grateful for the bumpy journey, it's the secret weapon keeping the island blissfully under the radar.
