About Mann Creek Campground
Overview
Mann Creek Campground is located near the Mann Creek Reservoir in the foothills of the West Central Mountains in western Idaho near the Payette National Forest. The reservoir is a popular boating and fishing destination.
Once on-site, you may be able to pay for your campsite(s) by scanning a QR code using the Recreation.gov mobile app, and the Scan and Pay feature. If this option is available, you will need to first download the free Recreation.gov mobile app https://www.recreation.gov/mobile-app prior to your arrival as some remote areas have limited or no cellular service.
Recreation
The reservoir offers 283 surface-acres of water and five miles of shoreline, although the water level fluctuates seasonally. Visitors enjoy boating, canoeing, swimming and trout fishing.
Facilities
The campground offers 13 sites, two of which are accessible and six sites are available for advanced reservations. Picnic tables, some of which are covered, and fire rings are provided, as are vault toilets and drinking water. Drinking water is often not available in late summer and fall; please call ahead to confirm availability. Roads and most parking spurs are gravel. The campground loop and two accessible sites are paved.
Natural Features
Mann Creek Reservoir lies in the rolling and arid foothills of the Hitt Mountains. At an elevation of 3,300 feet, the area is hot and dry in the summer months. Large shade trees help block some of the intense sun, but shade is limited.
Getting there
From Weiser, Idaho, take Highway 95 north for 12 miles, then take the Mann Creek Road north approximately 2.5 miles to Mann Creek Reservoir and the campground.
