I didn't report any expectations, just a tour bus passing by. But the fact is that the sulfur yellow mountain is more shocking than the Hell Valley, and the fog of many outlets is very large and accompanied by the uninterrupted roar. You can also see the hot spring water from the small hole to the outflow. And you can get close to the vent of sulfur vapor (but be careful not to get too close), and the experience is much better than the Hell Valley that can only be seen from a distance. The large open space next to it and the snowy mountains in the distance also make up a picture that has a very independent feeling, suitable for patting.
