The place
the agency’s own description · what’s there
In the agency’s own words
Mortimer Gulch campground is located close to Gibson Resevoir with 26 campsites available for use. 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. It is highly recommended that a 4WD vehicle is used to reach the cement boat ramp (1/2 mile away). 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.

Phone before you drive
recreation.gov publishes no availability for a campground you can’t reserve, so there’s no thirty-night reading to draw here. The season bar above is what the agency does publish.

What you actually pay
“$15/night for single unit & $5.00/night for an extra vehicle.” · the U.S. Forest Service’s own fee record
Derived by CAMPANAC: the lowest per-night amount the agency’s fee record states ($15), and no booking fee, because this campground takes no reservations. A weekend here means Friday and Saturday night. Optional charges (an extra vehicle, a second tent, a dump-station fee) are listed separately and aren’t in this total.
