The names Thien Ha Cave/ Thien Ha Grotto/ Galaxy Cave/ Galaxy Grotto refer to the same tourist attraction located in Son Ha Commune, Nho Quan District, Ninh Binh Province, North Vietnam. In 2007, local people found a cave with small entrance, covered by trees and tall grass in Tuong (General) Mountain which belongs to Trang An Mountains System. This mountain shapes like a guardian who is believed to protect the Ancient Hoa Lu Citadel of Dinh and Le dynasties. Being astonished by the natural beauty of stalagmite, stalactite, and by the creation of Mother Nature, local people named it Thien Ha which means “galaxy” in English.
To explore Thien Ha Cave, tourists will start with a 1km boat ride on a small canal from Son Ha Commune, then continue walking on the 500m stone road leading to the Tuong Mountain to get to the gate of the cave.The cave is 700m long, consisting of 200m dry cave and 500m water cave. Tourists will be visiting this cave by both on foot and on small boats rowed by local women. The 12.000 m2 interior (as big as Sung Sot/Surprising Cave in Halong Bay) homed to a group of ancient Vietnamese people. Lots of shellfishes, pottery pieces, animal bones, tortoise shells, and other traces and antiques have been found here. Thien Ha Cave, now, still homes to thousands of bats.
