Good trails around park headquarters. No camping allowed, and accommodations are available only at the near-by town. Barra del Colorado North of Tortuguero. Similar to Tortuguero, but better for waterbirds. Excellent trail system, and first quality guides.
Accommodations are limited.
Last Christmas count was 425 bird species. On the Interamerican Highway, before San Isidro del General. Parque Nacional Manuel Antonio Reached by road from Quepos, Pacific Coast. Beaches, rocky shores, forest. Trails well marked, only for the well-fit hikers.
