USFS · Campground · Free
4 campsites near the South Fork of the Teton River. Some fishing for brook, rainbow, and cutthroat, though all populations are low. Go 1 mile west to the end of the road to the South Fork trailhead, and hike in the short distance to pristine Our Lake, near the border of the Bob Marshall Wilderness. Our Lake is a fantastic place to see mountain goats year round, as well as the ever-entertaining pika and yellow-bellied marmot. Never approach or feed wildlife. Bears may frequent the area; keep all food out of sight in approved containers and remove all food from area after eating. Mandatory food storage is required.
