Mill Dam Group Campground operates as a seasonal group camping facility (October 1 - March 15) accommodating up to 150 people, with amenities including picnic shelters, group grills, flush toilets, and a parking lot for 70 vehicles.

An adjacent boat ramp provides direct access to the 168-acre Mill Dam Lake for motorized and non-motorized watercraft, though fishing from the bank is prohibited.

During off-season months (March 16 - September 30), the site functions as a day-use recreation area with swimming beach access; reservations are required for group camping through Recreation. gov.
