If hiking Sendero Los Quetzales or Volcán Barú in Parque Nacional Volcán Barú [1] is too ambitious, try the Bajo Mono loop, a scenic, 20-kilometer paved road. It features lush forest, dramatic volcanic cliffs, and a valley with a pretty river flowing through it.
It’s easy to flag down a bus if you get tired. Be careful—many of the truckers plying these roads seem to have a death wish. Take food and water, as there’s no place to buy them during this hike.
The Bajo Mono loop starts north of Boquete [2]. Follow Avenida Central and keep left at the fork past the church. The loop is well marked. It’s also possible to bike or drive the road.
