Fodor's Expert Review Piedras Blancas National Park

There is some good birding in the dense forest here, which is also an important wildlife corridor connecting to Corcovado National Park. Follow the main road northwest through the American Zone and past the airstrip and a housing project. The place where a dirt road heads into the rain forest is great for bird-watching. There are marked trails from the entrance near the marina, but the park is best explored with a guide; the best birding is along the road.
