Holter Dam Boat Ramp provides access to Holter Lake on the Missouri River, located approximately 45 miles north of Helena near Wolf Creek, Montana.

The ramp features a large concrete launch with courtesy dock and day-use/overnight dock slips available for campers, making it convenient for both motorized and non-motorized boating.

The nearby Holter Lake Campground (52 paved sites, $25/night) and Gates of the Mountains Marina (public ramp $10/day) offer additional facilities and access points in the area.
