Sendero los Quetzales in Boquete, Panama

Sendero los Quetzales is arguably the most famous hiking trail in Panama, and one of the more famous in Central America. Located in Vulcan Baru National Park, t's one of the only places where you're almost guaranteed to spot a Resplendent Quetzal -- if you hike in the right season, and at the right time of day. Unfortunately, I did not.
