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.

Booking window6 months outBooking opens 6 months ahead; today unlocks arrivals through April 16, 2027. The agency publishes no reservable season in the record we hold, so the window may close earlier than that.recreation.gov

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
We hold no recreation.gov booking record for this campground, so we can’t say whether a booking fee applies.
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: 0.16 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.
