This US Forest Service campground operates from May through September with a no-pets policy, though spring flooding can delay some site openings well into the season. Harry's Flat sits in forested terrain near both creek and lake access, making it a practical boat launch point when water levels cooperate. One camper notes that half the sites may remain closed until floodwaters recede.
The campground's proximity to water creates both opportunities and challenges - while boaters appreciate the launch access, the seasonal flooding means availability can be unpredictable during early season visits. For those planning trips to the broader region, campgrounds near Lolo National Forest provide additional options. Check current conditions before arrival, especially in May and June when flooding risk remains highest.
Description
Located in the Rock Creek drainage, this campground is adjacent to Rock Creek, situated amongst ponderosa pine and Douglas-fir trees. This area is known for its blue ribbon trout stream and rugged canyon environment.
