Moose Flat Campground, Alpine, WY
Fly fishers targeting Greys River cutthroat and brown trout will feel at home here, especially midweek when sites open up. Trailers up to 30 feet fit, the vault toilets stay clean, and wild roses screen neighbors well enough that tight spacing rarely feels like it.
Cash or check only, no hookups, no dump station, and 23 miles of road between you and Alpine if something goes wrong. Weekend arrivals without an early start will likely find it full, with no reservation option and no backup plan.

Summer delivers the best conditions, with daytime highs between 65-80°F and nights dropping into the mid-30s to low-50s. July and August offer the clearest river conditions and most reliable weather for hiking. Spring mornings can still see frost, while September nights approach freezing. Pop-up afternoon thunderstorms are common in summer. The limited site count means early arrival or midweek visits work best during peak season.
Best season: July–Aug offer clearest river conditions, reliable weather, peak use.
