A Fairyland Fallen to Earth—Sanmenhai

Sanmenhai has developed seven stringed karst doline groups, which is a hidden attraction. It is not a 'blue hole' but is more impressive than a 'blue hole', with a blue-green color that is more astonishing than the sea. This place is acclaimed as a fairyland fallen to earth by millions of fans and travel blogger Fang Qi. Taking a boat into the sinkhole, traveling through the wonderful caves, there is the excitement of exploring a secret realm as well as the amazement of being close to the blue water. When the boat exits the cave, there is a delightful surprise of a different world. Looking up at the sinkhole, through the skylight to see the mountains, forests, and blue sky, there are scenes in the water, and the water is within the scene, peering through the skylight at nature's mystery. Location: Fengshan, Hechi, Guangxi, Direct navigation: Sanmenhai Scenic Area Tickets: Adult ticket 98, student ticket 45. As it is quite niche, the surrounding dining and other facilities are not very well developed, and the parking lot is not large, so it is recommended to visit during the off-season or when the weather is comfortable. The boats are divided into 6-person and 10-person boats, all manually paddled, and the speed is relatively slow, with the round trip taking about 50 minutes.
