Kayakers and anglers find direct access to Hebgen Lake at this 27-site Forest Service campground, where a boat launch and shoreline sites make water activities the primary draw. Located within Gallatin National Forest about 20 minutes from West Yellowstone's entrance, Lonesomehurst operates from mid-May through mid-September with full hookups available for RVs up to 45 feet.
The campground spreads along the lake's edge with sites varying dramatically in privacy and water access. Lakefront sites offer direct shoreline access, while interior sites like number 6 sit in full sun with limited shade until late afternoon. Joshua C. notes that "the problem with not having a spot on the water is not being able to access the water anywhere but the boat dock when the campground is full." Site 19 receives frequent praise for its lake views and privacy, while site 20 sits directly adjacent to the restroom facilities.
Electric hookups reach all sites, with potable water spigots distributed throughout rather than at individual sites. The pit toilets earn consistent praise for cleanliness, and bear boxes, fire rings, and picnic tables come standard. Motorized boats frequent the lake during peak season, creating noise that carries across the water. Signs at the boat dock warn of potential toxic algae blooms, though swimming restrictions may be limited to specific areas.
Mosquitoes can be aggressive during summer months, particularly in July when temperatures reach the upper 80s. "All in all, great campground if you can get a lake spot," summarizes Nicole B.. T-Mobile provides strong 5G coverage for those needing connectivity. Reservations are available and recommended, as lakefront sites fill quickly and some visitors stay for extended periods.
The campground works best for RV campers prioritizing water access and full hookups over hiking trails or wilderness solitude.
