Hell's Bells Trail is a hard, 15.7-mile (25.3km) out-and-back route located within the Seven Sisters Protected Area, a dramatic wilderness area between Smithers and Terrace along Highway 16. With 2,500ft (762m) of elevation gain and taking approximately 7.5–8 hours to complete, this is a serious full-day adventure. The trail travels via Flint Creek Road and provides alternate access into the middle of the Oliver Creek Trail system, bypassing the steep lower elevation gain of the Oliver Creek approach. The route passes through dense boreal forest, marshy and overgrown sections, and opens up into a spectacular alpine landscape with stunning views of the Seven Sisters peaks, Mt. Quinlan, Paleo Peak, and the surrounding Coast Mountain ranges. Wildflowers are abundant in summer and wildlife sightings — including bears — are common. The Seven Sisters Protected Area sits on the traditional territory of the Gitxsan and Tsimshian peoples.
