Barr Lake State Park Access provides a boat ramp located on the east side of the lake accessed through the main entrance, accommodating sailboats, hand-propelled craft, and motorized boats with 10 horsepower or less.

The ramp serves the north half of the lake where boating is permitted, with a daily vehicle pass ($10) required for entry; note that water levels fluctuate seasonally and the ramp may close during low-water periods.

The park also offers ADA-accessible fishing piers and is open daily from 5 a. m. to 10 p. m. , with a Nature Center and ranger station nearby for visitor assistance.
