For an affordable jaunt to Central America without skimping on beach bliss or culture, head to Nicaragua. Admire architecture in Granada, go volcano boarding (yes, volcano) at Cerro Negro, explore the Somoto Canyon, or take a cheap surf lesson at Playa Maderas. This diverse country has a lot to offer by way of relaxation, cuisine, city and night life, and adventure. Oh, and the beautiful landscape doesn't hurt either.
