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 this receipt · 4
Booking fee, change fee, cancellation fee, no-show: Rules and Reservation Policies, Recreation.gov, the published fee schedule, curated by hand into lib/reservation-fee-schedule.json (9 rows, each carrying its own verbatim sentence). The publisher states these policies were last updated September 2019. · Sep 9, 2026
The two totals: Derived by CAMPANAC by adding the agency’s own published nightly rate to recreation.gov’s own published reservation fee. Both components are cited above; the addition is ours and is shown only where every component is known. · Sep 9, 2026
Who keeps the booking fee: Recreation.gov facility policy text, Dead Swede Campground (facility 234221) · Not on the national policy page. This is agency policy text recreation.gov publishes on individual campground pages; this site holds it verbatim on 45 active campgrounds (campground_rules.cancellation_description, scripts/load-facility-rules.mjs). · Sep 9, 2026

How we know
every fact on this page, and where it came from
Right now: Today falls inside the season the agency publishes, and it has posted nothing else. That reading is ours. The U.S. Forest Service’s own database, though, flags it not open with no reason or date; the flag is named under How we know all this.
Listed not open: USFS EDW Recreation Opportunities, openstatus field: a not-open flag in a database, with no reason and no date published; read there since Sep 9, 2026. A flag, not a notice, so this page doesn’t call it a closure. · Oct 16, 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.
