Its eruptions are characterized by ample of volcanic flow, which have formed a lava lake in the crater of the caldera. One of the latest eruptions occurred in 2015, causing water contamination due to ash fall; the lava also permanently modified the shape of caldera. You can book a glass-bottom boat tour or hike the 2,000 m (6,562 ft) trail and explore the mountain by yourself.

By multiple landscapes, and final passage is awesome on the crater of's active volcano.
Climbed this twice, on two separate work trips to Comoros. Makes for a very long day hike of about 15-20 miles and about a 5000-6000 ft vertical climb depending on where you start and finish.. We started both times at about 2800ft. You have to start very early (before sunrise) to get through the very hot (jungle) area in the lower areas. After several hours you break out at about 4000ft into a open alpine meadow. Great views and the temp goes way down. A few more miles will take you to the top of the rim. From there you can go down into the huge crater to check it out. Much colder and windy on the top. You need to bring a jacket for the top it was pretty cold with the wind. Great views in every direction. You have to be careful in the crater as there are some dangerous areas. We were escorted by two army guys both times who knew these areas. The biggest thing is to bring at least 4 liters of water as there is no where to get water once you're on the trail.
hello this is awsome
