When do reservations open at Hahns Peak Lake Campground - Medicine-Bow Routt NF (CO), Medicine Bow-Routt NFs & Thunder Basin NG?
- Booking window
- 14 days to 3 months ahead
- Releases
- Daily
Sites here open in two waves: 3 sites 14 days ahead, released daily, and the rest 3 months ahead, released daily at 7:00 AM PT.
For sites booked 3 months ahead, the next arrival date, Jun 22, 2027, opens on Feb 25, 2027. From Sep 18 to Sep 30, 2027, sites are first come, first served: no reservations are taken for those nights. Sites with a shorter window are released only that close to arrival, at a time the provider does not publish, so they show no availability before then: that does not mean they are sold out.
Closed for 2026. Next year's Open Season: Jun 22 - Sep 17, 2027 · Last checked Oct 26, 2026
