Aside from the howler monkeys and sloths in the tropical humid forest, you can see angel fish and brain coral in the water. Cahuita is one of the more pleasant parks to hike through since it runs primarily along the beach. The hike takes you through this often swampy forest on a well - defined path. Help the local conservation effort by hiring a local guide. Several bilingual guides are available and aid in keeping impact on the National Park as low as possible.
