Elk Mountain Trail is a 6.8-mile out-and-back from the Fielding access near US 2 to a 7,835-foot summit, with roughly 3,300 feet of climbing. Give it six to seven hours. Other published totals reach 7.4 miles; allow for the longer estimate if you need a planning buffer. The route climbs through timber, passes Fielding Patrol Cabin, then turns onto a steeper summit path. After a long forest stretch, the upper slopes open below the top. This is a hard, sustained climb for a full day, not a short viewpoint walk. The stored line traces the one-way corridor once; the mileage includes returning by the same route.
