East Pioneer Mountains
Tweedy Mountain Loop
Tweedy Mountain is the highpoint of the East Pioneer Mountains and 8th highest point in Montana if you exclude the Beartooth Mountains. There are several routes to the summit but the simplest and most popular starts from the Gorge Lakes trailhead on the east side of the range. The route follows the main trail for several miles before heading off-trail up to South Gorge Lake and finishes with a fun, albeit steep, scramble up Torrey’s northern flank. It is possible to skip South Gorge Lake and head straight to the summit but this will not shave off much time and you’ll miss out on the beauty of the lake. Alternatively, it is possible to bushwhack to Barb Lake from the same trailhead. The final ascent from Barb Lake is much simpler than the previous route but the bushwhacking can be miserable at times. These two routes could be combined to form a nice loop around the peak. Torrey could also be climbed from a base camp at North Gorge Lake or Torrey Lake on the west side of the range. The last mile to the trailhead requires high-clearance but up to that point it should be accessible by most vehicles although the road is a bit long and bumpy.
