This place is the one which interests me the most in Mui Ne.
It is located just before the village of Mui Ne, and you have to visit it walking.
The plus of this place is that there is a small river with red sand and you can walk inside with bare foot to visit it. Apparently, the more you walk and the more the countrysides are amazing.
To get there, you should pass under the bridge and follow up the river. Otherwise, if you go by another entrance, some people might ask you for an entrance fee whereas they should not.
