Wonderful, magical hikes through the cloud forest. There's no problem with the heat here, as temperatures are always cool. Cahuita National Park. Caribbean coastal hiking through easy, level terrain. Cabo Blanco Nature Preserve.
Easy day hikes through open woods, with plenty of monkeys to keep children excited.
Bicycling Costa Rica is definitely not a bicycler's paradise. On the other hand, we biked a portion of it, an experience that led to a number of memorable adventures. This is not for the uninitiated. As an introduction to bicycle touring, it would be a nightmare, but for experienced families it can be a real adventure. Heat and road conditions are the two main issues.
