Lake Amistad Access provides multiple boat ramps and facilities managed by the National Park Service along the 64,900-acre reservoir near Del Rio, Texas.

A lake use fee ($4/day, $10/3-day, or $40/year) is required for all motorized watercraft, with passes available at the Visitor Center or automated fee machines at select locations.

Key access points include Diablo East (long, steep 4-lane concrete ramp), Rough Canyon (usable at most water levels), Box Canyon, and several others, though availability depends on lake conditions and water levels.
