We passed through that area last year on our way to ride the Magruder Corridor just north of there. There’s several good looking trail systems there as well as some great Lewis and Clark history along the Salmon....
Probably half a year too late, but there are some fun trails and dirt roads all around in that valley. Pretty much every canyon has something. Old, abandoned mining towns, beautiful lakes, and gorgeous mountains. There is a trail there where you can ride all the way up to some alpine lakes at almost 10000'. Very fun place. We go yearly.
