The route starts at the Carbon River Entrance on an old roadbed that has been closed to vehicles since flood damage in 2006. The Ranger Creek junction is 3.6 miles from the entrance, then the falls are another mile uphill. The full Green Lake hike is 10.8 miles round trip with 1,300 feet of climbing. Ranger Falls is about 0.8 mile before the lake, so it makes a substantial out-and-back on its own. At the junction, follow the signed 200-foot spur to the overlook; nearby informal paths descend but do not reach the viewing point. Bring food and drinking water for the long approach, and treat any natural water before drinking.
