Mortimer Gulch Campground, Rocky Mountain Ranger District, Helena-Lewis and Clark National Forest, Montana
Fall foliage campers and fly-fishers targeting rainbow and cutthroat trout in Gibson Reservoir will get the most from this place. The two trails out of camp, including the 17.5-mile North Fork route into the Bob Marshall Wilderness, give backpackers a real jumping-off point, and
No potable water on-site means hauling everything in from Augusta, 26 miles out. The unpaved access road is rough enough that reviewers specifically flag it, and getting a boat to the ramp requires a 4WD tow vehicle. If vault toilets are a dealbreaker, there's nothing else here.

Fall is the main draw. Aspens peak in late September or early October, turning the lower loop bright gold against the dark firs. Daytime temps run 45-60°F with nights dropping into the 20s-30s°F. Bugs taper off after Labor Day, and crowds thin out, though services get reduced too. Early September weekends still see moderate use. Weekdays are quieter. Winter gets cold enough to require serious gear. Summer brings comfortable temps for hiking and fishing under clear skies.
