When do reservations open at Cottonwood Point, Marion Reservoir?
- Booking window
- 4 days to 6 months ahead
- Releases
- Daily
Sites here open in two waves: 34 sites 4 days ahead, released daily, and the rest 6 months ahead, released daily at 7:00 AM PT.
For sites booked 6 months ahead, arrivals through Apr 27, 2027 are open now, and Apr 28, 2027 opens on Oct 28, 2026. 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.
