Top 14 in Top 15 best volcanic climbing places in the world.
recorded volcano Aso erupting in November 2019
This is Japan's largest active volcano, which is sure to be an adventure that should be at the top of your list. There are three trails you can use to get to the top, one of them doesn't actually lead to the volcano (hint: don't take the trail on the left). The hike itself can take anywhere from an hour or three depending on which trail to choose and how many stops you rest at along the way. There are actually five separate volcanic peaks here, and Nakadake Peak is the most active peak that spews a continuous stream of sulfuric gas. If you still want to get to the top of the volcano without the hassle of walking, the cable car is a reasonable choice for you.
