Rumbaugh Ridge Access provides a primitive dispersed camping area on the south shore of Hebgen Lake with 4-5 designated sites, including a rutted boat ramp for lake access.

Access via Denny Creek Road requires high-clearance 4WD vehicles due to deep ruts and tight corners; trailers over 20-30 feet and larger RVs are not recommended.

The site is free, first-come first-served, and open year-round, though visitors should be aware of potential toxic algae blooms in the lake water and severe mosquitoes/horseflies during summer months.
