Hi, I will be traveling bike commuting from the south of Costa Rica to the western part of Panama, entering Panama through the Paso Canoas border. In Panama I'm planning to visit Volcán Barú and Boquete at least, however I was also considering to ride the bike to the caribbean side passing through Chiriquí, Almirante, Changinola and entering Costa Rica again through de Sixaola/Guabito border. In Sixaola I would take a bus back to San Jose (where I live).
I am planning to ride the bike in rural or paved roads that don't have much traffic (for my safety), however looking at the Panama highway maps I am not sure if it's possible to get from Boquete to Chiriqui/Almirante/Changinola using those kind of roads? I don't care if it takes a little bit longer.
