This trip is considered a full-day tour (usually). It is a 6-8 hour guided hike to the 2nd largest but hottest boiling lake in the world. The hike consists of a variety of different landscapes, rivers, hot springs, and fumaroles. At the end, a swim through the titou gorge is optional. It is a 5 - 10 minute swim through a beautifully carved slot canyon with a powerful waterfall at the end! The hike is considered relatively challenging.
