The hut has been successfully modernized, combining old and new. Not much of the old hut's charm remains, but everything is now more spacious, well-designed, and bright, including a wonderful lounge with panoramic windows. The hut can also be reached as a day trip by taking the bus to the dam and walking around the lake—with a coffee stop at the Chanrion Hut.

The path through the many galleries connected to the many waterfalls makes the route very attractive!
