Amistad National Recreation Area offers multiple fishing access points around Lake Amistad, with boat ramps maintained by the National Park Service at locations like Diablo East (4-lane concrete ramp), Rough Canyon (long, steep 4-lane ramp usable at most water levels), and several others, plus bank fishing available at select locations.

A motorized boat pass ($4/day, $10 for 3-day, or $40/year) is required for lake access, and fish cleaning stations are conveniently located at Diablo East, Pecos, and Rough Canyon to prevent lake pollution.

Water levels fluctuate seasonally, which may affect ramp accessibility at lower-elevation access points.
