The area is a volcanic area, rich geothermal and precipitation make the hot springs the hot springs on the island, known as "Japan's first soup". There are hot spring hotels and shops on both sides of the hot spring street, and many of the goods in the store are related to ghosts. Walking around the town, you can see many sculptures about ghosts, and there are various sacrifices in different seasons.

Walking along the mountain from Hell Valley, you will come to another scenic spot formed by volcano - Datang Marsh. A hot spring stream overflowing from Datang Marsh is available for tourists to soak their feet. Inside is black volcanic mud, soaking very comfortable.

Large, area is also; soup, Japanese hot spring bath is also; marsh, pool marsh is also; big soup marsh, a large hot spring pool is also. However, this pool cannot be soaked. The big soup marsh is one of the five deadly hot springs in the world. The hot spring water from the underground is high and there is a certain toxic gas composition. There is also one in Japan that is not suitable for soaking. It is Hell Valley Monkey Hot Spring, but Hell Valley Hot Spring Monkey is soaking. People are not soaking in the high probability is afraid of monkey siege... Datang Marsh is the source of the nearby hot spring hotel, and some spring water is also introduced in the local area. After cooling, tourists can take a foot bath and soak in the marsh. Of course, this place is still not recommended to stay for a long time. The gas coming out of the ground is harmful.

Datangmarsh, located near Hell Valley, was originally the outlet left by volcanic eruption. The hot spring water here is high temperature, more than 100 degrees. It is used by all other hot spring hotels. It can be said that this is the source of Dengbie hot spring. You can feel this natural hot spring at close range. There are free foot-soaking pools for tourists to experience. If you want to enjoy the other hot springs, or go back to the hotel, many hotels can feel the pure Japanese soup.

In winter, Hell Valley was completely surrounded by snow and ice, and the way up the mountain was very slippery. It was stopped five minutes away from Datangmarsh, so I had to take some pictures in the distance to remember it. I hope to see the real face of Hell Valley when it is full of red leaves next year.

It is a volcanic crater relic. As the bottom of the crater continuously emits Sulphur Springs of about 130 degrees Celsius, it becomes a steaming small lake with water surface temperatures as high as 40-50 degrees Celsius. Take the bus to the entrance of Zutang at the Dengbie Railway Station or the Dengbie Hot Spring Bus Station. Get off at the entrance of Zutang. You can go to Datang Marsh along the Datang Marsh Trail.

The road from Hell Valley to Datang Marsh is not easy to walk. Especially when I went to Datang Marsh, it snowed. The road was rather rugged, and the road was slippery and muddy. You must be careful when you walk. Older friends don't recommend going deep. Safety comes first. For those who haven't seen it, the first time is quite shocking. Watching the misty smoke rising continuously is like a fairyland. Weather and time permitting, it's advisable to take a walk.
