The lush, peaceful country of Limon, Costa Rica, has long been a well-kept secret among biologists and beachcombers. And it's easy to see why. More than 27 percent of Costa Rica's amazing terrain is designated as national park, biological reserve, wildlife refuge or some other category of protected area. Home to hundreds of thousands of species of exotic flora and fauna, this special fertile land is also a haven of spectacular beaches that stretch for miles, jungle rivers perfect for rafting and kayaking, and wonderful historic ruins.
