The Cerro Verde Cloud Forest Trail is the gentle option in Los Volcanes National Park. It loops through humid highland forest around the extinct Cerro Verde cone, with viewpoints that frame Izalco, Santa Ana, and Lake Coatepeque when the cloud lifts.
This is the walk to choose if you are not doing the Santa Ana crater hike or if weather closes the higher routes. The trail is short, but the forest is lush and the air is a relief after the heat lower down.
