Tips for Visiting El Imposible National Park
- Hike the Sendero la Campana and keep an eye out for the jagged 'hanging' cliff vistas-many visitors miss the less-marked viewpoints.

- If birdwatching, take a guide who can help with calls and local ranges; El Imposible supports resplendent quetzals and numerous endemics.
