Campground Overview
The only campground in the park open year-round, Mammoth Campground—elevation 6,200 feet (1890 m)—is located five miles south of the park's North Entrance. Scattered juniper and Douglas fir trees provide shade during hot summer months. The campground is close to fishing, hiking, and the Mammoth Hot Springs. Great wildlife viewing opportunities abound with elk and bison occasionally passing through the campground. The campground is run by the NPS.
Reservation Info
Sites are reservation-only from early April to mid-October and first-come, first-served from mid-October to late March on Recreation.gov. Individual campsites at this campground can be reserved up to six months in advance. Reservations open on a rolling basis, meaning you can book your site exactly six months before the date of your stay, as long as reservations are available for that time.
Rules
Fire/Stove Policy
Wood and charcoal fires are permitted, though special fire restrictions are occasionally put in place when the danger of wildland fires is great. If you plan to light a fire in the park, please ask about current fire restrictions at the entrance station when you arrive or email our Visitor Services Office immediately prior to your visit. Propane grills and stoves are normally not restricted.

Overnight camping or parking is only allowed in designated campgrounds or campsites. Campsite occupancy is limited to six people per site. Checkout time is 10 am. Camping is limited to 14 days from July 1 through Labor Day, and 30 days for the rest of the year. There is no stay limit at the Fishing Bridge RV Park.
