Farewell to Hell Valley, located in Hokkaido, is the most famous hot spring birthplace of Hokkaido. It was originally a volcanic crater, perennially filled with volcanic gas with a strong odor of rotten eggs. As soon as it entered the crater, it could be smelled. From a distance, it could be seen a mass of white fog, bursts of hot air, the color of the mountain body was black and yellow, which was the traces of burning and corrosion. It specially repaired the wooden trestle road for tourists. Along the trestle road, it could go up the mountain, so it was a very strange sight. It's called Hell Valley. We will be in winter, covered with snow, which adds a sense of mystery. There is a spring named "Tiequan Pool" which is a geyser. The temperature of the ejected water reaches 80 C, which varies with the period. Farewell to Hell Valley will also organize some activities along with seasonal changes. In a word, all seasons here are fun and must come.
