The campground is on the Seneca Creek Trail in a meadow area along the Seneca Creek. Campsites are situated in and around the meadow with multiple trail junctions near by. Campsites are primitive (flat area for a tent and basic rock fire pit) for backpackers hiking in the Spruce Knob Recreational Area. I stayed there one night hiking down the Seneca Creek Trail. The trail has various campsites throughout the length of the trail (not just at Judy Springs) and some good fly fishing spots (saw trout running up rapids multiple times).
Second campsite was about 50 meters south of the the Seneca Creek Upper Falls (location near: 38° 46' 2.5932'' N 79° / 30' 27.1764'' W). This campsite also had two other falls direct next to it. This was an incredibly beautiful campsite. Third night, stayed at a campsite 0.75 miles from the trailhead parking lot (near: 38° 43' 7.0104'' N 79° 32' 41.1612'' W).
