Dong Thien Ha (Galaxy cave)
Galaxy grotto Eco-Tourism area consists of two main activities: Thien Thanh cave and Thien Ha grotto. To get to Thien Thanh cave, you will conquer 157 steps to reach the cave gate. This is a dry and small cave, spread around only 50m, but its beauty will certainly amaze you.

Venture underground and gaze with wonder at the ancient beauty of the cave. The stalactites, with their different shapes, gleam like a dance of color. The layers of light will lead you further to the bottom of the cave where a giant stalagmite stands, described by locals as “the column that props up the sky”.
From Thien Thanh cave to Thien Ha Cave is only a few hundred meters. Thien Ha cave is mostly a water cave, though there are dry areas also. I found the wet cave to be far more impressive. Thousands of unnamed stalactites, sparkling along the arch of the cave ceiling make anyone feel like they are in a galaxy of colors. Many stalactites have unique shapes, impossible shapes formed over millions and millions of years.
Sometimes people name them after flowers or animals, but mostly these formations defy explanation, for they are simply too beautiful to describe. This cave is not without its local residents; you will see thousands of bats hanging on the cave ceiling. They are shy and gentle creatures and will fly away when your boat reaches near.

Overall, the Galaxy cave system is an absolutely breathtaking adventure, and though many tour operators may not go there, it is truly worth making the effort to come here. You won’t be disappointed!
