I like nature and peace of life. The name of the farewell comes from the ancient Ainu word "", meaning white turbid river; Hell Valley is the source of the Noboribetsu hot spring, and is also the most famous attraction of Noboribetsu Onsen. The volcanic landscape is extremely spectacular. Hell Valley is a volcanic eruption site where volcanic gases eject from the surface of the gray-yellow rock, and the surrounding air is filled with strong sulfur odors, and the grass is not born here, hence the name Hell Valley. Surrounded by mountains, the smoke is lingering, and the devils and ghosts of the local specialty holding the mace are placed in it, as if they have entered the ear and nose. The local area has also specially developed a summer night tour route - the WISP Road, with small lights on both sides of the plank road in Hell Valley, looking from afar, winding around, the lights flickering. The end of Hell Valley has a geyser. Every once in a while, spring water will erupt, and the temperature of the spring here can be 80 degrees. Below the Hell Valley is a hot spring street with all the hotels and restaurants on the street. If the itinerary and time are relatively generous, it is best to stay here for one night, soak up a hot spring and enjoy it. The best time to visit the Hell Valley in Noboribetsu is 6am every day. Team visitors will not appear. Most of the ordinary tourists are still asleep. The entire Hell Valley is empty. You can see the life in the rising sun. Purple smoke effect. The big soup marsh continues to go deep, there is a natural foot bath, and it is very refreshing to get tired.
