Ask an AI about this campsiteOpens Grok already loaded with this site. It reads the same records this page is built from, and links whatever it tells you.
Ask about this camp →U.S. Forest Service lists this as a developed campground. Expect marked sites, a fee station or a reservation, and the usual campground rules. The dispersed-camping freedom of the surrounding forest does not apply inside it. What changes is conditions — roads, gates, closures, fire rules. Check those with the unit before you commit to the drive.

How it was placed
Developed FEE campground (not free) - review | auto:usfs-fee 2026-08-20: US Forest Service developed campground, agency coordinates, agency states a fee. No dollar amount in the agency record -- expect a charge and confirm the current rate before you go. Not field-verified. | Fee 2026-08-26: three agency figures, all current, none reconcilable from a keyless source. recreation.gov listing 233772 books this campground at $38 per night single / $76 double for the 26 Apr - 13 Oct 2026 season -- that is what you actually pay to reserve. The forest's own page prints $33 single / $66 double in its fee field and, in the concessionaire paragraph below it, "Currently $46 per night (+fees and taxes)". Budget $38 plus taxes and fees.
