Stop at the second two-track on the north side of Sucker Road about 3.6 miles west of US-45. Park at the gate and follow the two-track on foot. Road more-or-less dead ends after 3/4 miles at a swamp (it continues on to the northeast but is quite flooded). A short distance before the swamp there is an overgrown path on the right side that has a few scattered pink tape markings. If you can't find the path just head east from the end of the two-track, staying away from the swamp on your left, and you'll bump into Sucker Creek within a few hundred yards. Waterfall is located on the north end of Brush Lake.
