Mortimer Gulch Campground

Fishing for rainbow or cutthroat trout in the reservoir and in the North Fork of the Sun River is an excellent way to spend the weekend away during the summer months.

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.
