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

We hold no recreation.gov booking record for this campground, so we can’t say whether a booking fee applies.
What a stay costs
A night, and a whole weekendDerivedNothing

Derived by CAMPANAC: the agency’s own record says there’s no camping fee, and no booking fee, because this campground takes no reservations. A weekend here means Friday and Saturday night. Optional charges (an extra vehicle, a second tent, a dump-station fee) are listed separately and aren’t in this total.

How we know this receipt · 5
Sign price: Derived by CAMPANAC from the U.S. Forest Service fee record: a stated per-night amount only · Sep 7, 2026
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: 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.
