Gangara Valley, located in Nanjo City, southern Okinawa, is a mystical place formed by the collapse of a limestone cave hundreds of thousands of years ago. The valley is covered in a lush subtropical jungle, and the cave is adorned with beautiful stalactites and stalagmites. Exploring the mysterious cave or taking a forest bath while listening to the birdsong will surely soothe your daily fatigue. It is also popular as a power spot where you can feel a mystical energy. There are various ways to enjoy your time there, such as joining a cave exploration tour, observing nature, or exploring historical sites. We recommend exploring deep into the cave with an expert guide or visiting ancient ruins and imagining the lives of the ancient people. There are also other tourist attractions in the vicinity, such as the Cave Cafe, Nanjo Castle, and斎場御嶽. The Cave Cafe sometimes holds concerts and events within the cave.
