Go if

Anglers chasing Henry's Fork trout, birders hunting trumpeter swans and sandhill cranes, or families who want a structured base near Yellowstone with real beds. The Becker Backcountry Yurt gets consistent praise for scenery and character.

Skip if

Tent campers are out entirely, there's no tent option here. RV hookups don't exist either. If you're expecting a traditional campground, this is a cabin-and-yurt park with a small site count, so book well ahead or you won't get in.
