Sylvan Lake State Park Access provides entry to a 42-acre mountain lake at 8,500 feet elevation with a boat ramp located on the north side of the lake between the cabins and day-use area, accessible via Brush Creek Road/Forest Road 400.

The park requires mandatory boat inspections and offers non-motorized and electric motor boating, with paddle boards, canoes, and kayaks available for rent ($40/day).

A visitor center 10 miles south of Eagle on Brush Creek Road provides information, passes, and amenities including showers and flush toilets (summer only).
