Mancos State Park Access provides entry to Jackson Gulch Reservoir, a 216-acre water body offering wakeless boating and hand-launched watercraft opportunities.

The park features a concrete boat ramp on the southeast side of the reservoir (currently closed seasonally mid-October through May due to low water levels), with hand-launched craft still permitted year-round.

Access is via County Road N approximately 4 miles east of Mancos, with a visitor center, picnic areas, and 33 campsites available for day-use and overnight visitors.
