    NPS describes the usual Bumpass Hell hike as a three-mile round trip from the Bumpass Hell parking area: the first mile is mostly flat, the trail then drops into the basin, and a boardwalk provides close views. A second trail skirts the north edge and continues to a second overlook; most hikers return from there. The page also says the basin is accessible by a trail from Kings Creek. Within the same page, the parking area is described as both seven and eight miles from the Southwest Entrance, duration as two hours and 90 minutes, descent as 200 and 300 feet, and surface as packed gravel and hardpacked dirt and rock.
