Hiking Cerro Chato from Arenal Observatory.
Cerro Chato hike took us about 3.5 hours both ways. The last 200 meters you are hiking down toward the crater lake. It was cold and muddy but still, it was a unique chance to swim in an active green crater lake. While hiking Cerro Chato we met many groups of people going down alone but some of them said it was deadly scary! Some sections of the trail are narrow and full of slippery roots. The scenery is gorgeous but you should know you are entering higher-altitude cloud forest.
One of the top attractions is Poas Volcano – check full guide on how to get there HERE.
