BL1 Tien Son

Tien Son is a show cave. The entrance is located along road Nr 5, the road that touists follow from Tam Duong to Sapa. From the entrance porch, an underground river can be followed upstream until a sump, where the gallery is only a few centimeters high.

This cave is a place of worship: everywhere, incense and broken speleothems can be found.

On request, we made it's topography.
