The info below is from

FALLS OF SENECA [FALL]: Swimming place at bottom of falls in Seneca Creek. About a 3-4 mile hike. No fee. Unofficial. Bathing suits unknown. LAT, LON lat=38.8184, lon=-79.4909(source: Topozone) (accuracy:exact) LINK TO GOOGLE MAP. To get here: From the Seneca Rocks visitors center, turn west (right) onto RT 33/55 and go about 5 miles to County Rd 7 on the left (south). Go about 2 miles south on RT 7 to the trailhead on the left. Park and hike up this trail along Seneca Creek (must cross creek several times) about 3-4 miles to the falls. SENECA BACKCOUNTRY TRAILS MAP. Along this trail, you will encounter a locked gate and a sign saying that the property belongs to a hunt club. This is a well-travelled hiking trail and many hikers continue on around this gate to the falls. Pretty confident. Partially verified- hiked up to the gate mentioned above but never proceed to the falls, 10/2000. Updated 2/4/2003

UPPER FALLS OF SENECA CREEK [UPPER]: Hike about 5 miles to the Upper Falls of Seneca Creek. A 12-15 feet high falls drops into equally deep pool of emerald green (cold) water. No fee. Unofficial site. Bathing suits unknown. PHOTO. LAT, LON lat=38.77175, lon=-79.50828(source: DeLorme) (accuracy:approximate) LINK TO GOOGLE MAP. To get here: you could continue hiking up Seneca Creek from the Falls of Seneca but it is a long way. A better way is, from the Seneca Rock visitors center, go south on RT 33/28 to Riverton then 2 miles more to turn right (west) on CR 33-4. Continue onto FR 112. Follow FR 112 to Spruce Knob then 6 miles more and park at the Seneca Creek trailhead. SENECA BACKCOUNTRY TRAILS MAP. Hike north on this trail about 5 miles to the Upper Falls of Seneca Creek. Very confident. Not verified. Updated 2/4/2003.
