[Hiraodai] Karst topography and limestone caves

The mountains have a karst topography with impressive limestone. It's so grand and beautiful! On the way up by car, there is a limestone cave called Senbutsu Cave, which is open all year round. It's warm even in winter. To enter this cave, you must go through water up to ankle height, and sandals are available for rental. It's a very adventurous experience, and it's very interesting ☺️ The karst mountains also have hiking courses that take about 3 hours, so it's a place where you can enjoy nature all day. #tripmemory2022 #breathtakingview
