Amistad Boat Ramp (also known as Rough Canyon) is a long, steep 4-lane concrete ramp located approximately 20 miles northwest of Del Rio off US-277 North, usable at most lake levels and open year-round.

The facility offers camping, picnic areas, parking, handicap access, restrooms, cleaning stations, courtesy docks, and boat gas, making it a well-equipped access point for motorized boating on Amistad Reservoir.

Note that all motorized boats require a lake use pass ($4/day, $10/3-day, or $40/year), and the facility is maintained by the National Park Service.
