The place

the agency’s own description · what’s there

In the agency’s own words

This campground, on the shoreline of Cooper's Lake near Ovando, Montana, is a semi-remote, developed campground which offers shady rest and a beautiful view of the lake and adjacent mountains. The Bob Marshall and Scapegoat wildernesses are 7 miles away by trail. Big Nelson has tent camping only. No camping is allowed in the parking lot and no trailers are permitted.

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.
At this time we are not charging any use fees at this recreation site.
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.
Elevation: USGS 3DEP elevation point query at this campground’s coordinate · Sep 7, 2026
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: 0.027 mcd/m² of artificial all-sky glow, ranked against the 501 rated federal campgrounds in Montana · Sep 8, 2026
Sky-glow model: Duriscoe, Anderson, Luginbuhl and Baugh (2018), a simplified model of all-sky artificial sky glow derived from VIIRS Day/Night band data, the National Park Service sky-glow model
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.
