This is Dominica's most famous oddity – a boiling lake. The murky lake sits in a cauldron and when active is bubbling due to emitting gases from the molten lava deep underground. The lake can only be reached by a trek that takes about 6 hours return. It's not an easy trek, but very rewarding with lush rainforest, amazing views over the natonal park, steamy mini geysors, and, of course, the second largest boiling lake in the world (the largest is in New Zealand). The trek goes through a lot of elevation and though there are steps of wooden beams, it can get very muddy and slippery. Some parts need to be scrambled (with hands and feet), creeks need to be crossed several times, and the last section up to the crater rim can be hard to find unless you have a guide or have downloaded a gpx file to your gps device. The trek should not be started after 11 am and begins at Titou Gorge.
