We were just driving along and saw a brown sign. Took the road and came across this very cool gem of a site. We were there on Sept.24. So it wasn't open. But still very interesting to read the signs and admire the amazing stone buildings. The bridge story is very interesting also. They have done a lot of work there and seem to have more planned There is a great camping area there with nice clean toilets. Good job to everyone involved. Beautiful country. Very glad we stopped
