Lone Tree Campground (Clark Canyon)
Free primitive camping on Bureau of Reclamation land at Clark Canyon Reservoir, about 20 miles south of Dillon, Montana and right off I-15 -- a genuinely free stop on a stretch where most options charge. Reclamation runs this reservoir itself, and its own records show no camping fee, no entrance fee, no boat-launch fee and no parking fee anywhere on it. The ONE exception on the whole reservoir is the Lewis & Clark Campground/Marina, which has full RV hook-ups and a self-pay fee station -- that is a different campground from this one, and it is the only site Reclamation's own map marks with its "$ Fee Area" symbol. On the south end of Clark Canyon and, per Reclamation, "a popular area for group camping". Shelters, picnic tables, vault toilets, a hand pump, and fire rings. Access is by a gravel county road off I-15 or State Highway 324. Note: OpenStreetMap tags this site as operated by the State of Montana, but Reclamation's own brochure and map both show it as theirs -- we go with Reclamation. Reclamation does not publish a stay limit for these campgrounds anywhere we could find -- you will see "14 nights" repeated on camping websites, but that number does not appear in any Reclamation document, so treat it as unconfirmed and ask the Dillon Field Office. This is primitive camping: expect a vault toilet and, at most sites, a hand pump rather than tap water -- treat or bring drinking water. The reservoir sits at about 5,500 feet and is exposed, so it can be cold and very windy well into the summer. IMPORTANT: Reclamation's facilities record was last updated in 2017 and the brochure is undated, so confirm current fees and rules with the Bureau of Reclamation Dillon Field Office at (406) 683-6472 before you go.
