The place

the agency’s own description · what’s there

In the agency’s own words

A stay at the Cottonwood Campground enables guests to enjoy all the beauty and recreation offered around the Middle Fork Boise River and Arrowrock Reservoir. This tiny campground hosts 3 campsites. Weather is usually good from mid-May through late September and is easily accessible by car in good weather, although the road is sometimes rough and the drive can be seemingly long. Checking with the Mountain Ranger District, 208-587-7961, on road conditions before heading out is recommended. Natural Features: The campground is situated just north of the reservoir along Cottonwood Creek. Keep reading

There is at a switchback of Forest Service (FS) roads 268 and 377. It is located less than a mile along FS road 377. Wildlife watchers may want to look for deer and elk. Waterfowl, eagles and osprey are attracted to the river. Recreation: Cottonwood Trail begins nearby, leading to Bald Mountain. Arrowrock Reservoir is a premier fishing destination in southwest Idaho. It offers excellent trout fishing for rainbow and cutthroat trout. There are also good swimming holes. Big game hunting is a popular activity in season. The Middle Fork Boise River is just north of the campground and also offers great fishing.

Nothing to book, just show up

One of 1,623 federal campgrounds where the site still goes to whoever pulls in first. Get there before noon on a summer weekend.

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

The sign priceU.S. Forest Service
The U.S. Forest Service publishes no per-night rate for this campground that we can read, so there’s no sign price to print. That’s a gap in the record, not a free campground.
The booking feerecreation.gov
Nothing. This campground takes no bookings, so there’s no reservation fee to pay.
What a stay costs
The agency publishes no nightly rate for this campground, so there’s no total to show.

How we know

every fact on this page, and where it came from
Right now: U.S. Forest Service publishes no season and no closure for this campground, and it takes no bookings we can read. That’s a gap in the record and not a locked gate.

Night sky: VIIRS Day/Night Band annual cloud-free composite, VNL V2 2024 (Earth Observation Group, Colorado School of Mines), read at the published coordinate: 0.38 mcd/m² of artificial all-sky glow, ranked against the 523 rated federal campgrounds in Idaho · Sep 8, 2026

Cell signal: the Forest Service’s own campground description, read as text by CAMPANAC. None of this is a measurement. It’s what the land manager published about the place, and phones, carriers and weather all disagree with each other; treat it as a warning, not a promise.
