Pretty interesting to visit this area of Volcanoes National Park to see and smell the sulphur deposits along the trail indicating thermal activity. Its a nice walk down the trail so I would recommend it.
Your first experience of the power of nature as steam and sulphur permeates the air as you walk along side crevices in the earths surface allowing the gases from the volcanic activity deep beneath your feet to escape. Awesome.
see how the landscape has changed. you can smell the sulfur and see how the land has been destroyed. there are still steam holes and the land is fragile so don't go pass the barriers you could fall in
As you walk through the sulphur fields (stay on the trail for your safety) you are acutely aware that the volcano is alive beneath your feet. Even though it's not actively erupting at this time, it's still "breathing"!
We went this way on our walk to the crater rim. There are a number of steam vents with unrealistic color formations resulting from the sulfur vents. It was okay to view but getting to the crater is really what you want to see.
