Ryugashido Cave is a limestone cave totaling about 1,000 meters in length with a public area of about 400 meters. The average yearly temperature within the cave is 18 degrees Celsius; cool in summer and warm in winter, visitors can enjoy a pleasant tour beneath the earth. There are about 50 observation points in the cave, and the underground waterfall with a drop of 30 meters called the Grand Golden Waterfall is particularly popular. On site there is also a "foot water" facility visitors can enjoy called Yokita Cave, which uses natural cold air and cave water to create a footbath. This is an especially popular cool-down spot during mid-summer.
