Ask about this camp →U.S. Forest Service lists this site. On most of their ground you can camp away from developed sites pretty much anywhere — so treat this as a known-good spot, not the only one allowed. The unit sets stay limits and how far off road and water you must be. What changes is conditions — roads, gates, closures, fire rules. Check those with the unit before you commit to the drive.

The unit that manages Hwy191-48 Portal Ck Trlhd
Stay limits, road closures and fire restrictions at Hwy191-48 Portal Ck Trlhd are set by Custer Gallatin National Forest, not by the campsite — check there before you go.
Snow, and when this opens
The nearest automatic snow station is Lone Mountain at 8,820 ft, about 12 miles away. It sits about 2,931 ft higher than this camp, so treat it as a guide rather than a reading for this spot. We do not repeat a depth here, because any number we stored would be stale by the time you read it — the station publishes today's.
