Big Rock Falls is a an 80' tall waterfall into a nice deep plunge pool. It's accessed through a trail about 300 yards long down a 130' deep gorge. The trail is well built but slippery when wet. The place has good afternoon sun and plenty of rocks to sun bathe on. Take water and food since there's nothing nearby. It's self tour but the road is unpassable except by 4x4 during the wet season.
