There are excellent hiking trails and even backcountry camping near Coronado. Here are some of the best spots within an hour or so of Playa Coronado:
1. El Valle de Anton: the only town in the world inside a volcanic creator. There are amazing viewpoints all around the rim of the extinct volcano. There is great camping and eco-lodges in this area. The best hiking trails are Cerro Cariguana, Sendero Cerro Gaital and India Dormida.
2. Altos de Campana National Park: excellent hiking trails high in the mountains with spectacular views of Punta Chame, the Playa Coronado resort area and the islands in the Gulf of Panama. La Cruz Trail is excellent and you will find alpine camping around the national park.
3. Sarigua National Park: this was once the site of ancient civilization but deforestation turned it into a desert scrubland. It contains Sarigua, one of the country's most important pre-Columbian sites. This area hosted a fishing village 11,000 years ago and is the site of Panama's earliest-known farming community 1,500 years ago.
