Lolo National Forest Harry's Flat Campground

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.

Floods out

It gets really flooded out in the spring time. Some times half the site is closed for a while into the season until it dries up. Good place to launch your boat though and when it is open it’s great.
