When Mount Rainier campsites go on sale
Snowpack keeps the Mount Rainier season short, so demand compresses onto Cougar Rock and Ohanapecosh. White River never takes reservations at all. Here is how each one works.
Camp-Now watches sold-out Recreation.gov campgrounds for you, catches the cancellation, and holds the site in your cart while you check out.

How to book
Booking Mount Rainier, start to finish
- Where
- Recreation.gov. National park campgrounds are not bookable by phone during the reservation season.
- When
- Cougar Rock is already published into mid-October, so there is no later drop to wait for. Ohanapecosh has no 2026 reservation dates posted at all yet, which makes it a page to recheck rather than a date to plan around.
- Be ready
- Sign in, save a card and settle your dates and party size before the window opens. Popular weekends go in minutes, and the checkout you prepared in advance is the one that completes.
- Which campground
- Cougar Rock is the Paradise-side campground and the one most people want. Ohanapecosh is in the southeast corner, in old-growth forest, and about an hour away by road. They serve different trips, not the same trip twice.
- Book at least a day out
- Both reservable campgrounds cut off bookings one day before arrival, so a same-day cancellation cannot be picked up online. Watch for openings two or more days ahead.
- If you miss it
- Cancellations are the realistic second chance. They appear at any hour, cluster in the last two weeks before arrival, and are usually taken within minutes.
- Backup plans
- White River is first-come only and usually opens late June, and Gifford Pinchot National Forest has campgrounds along the southern approaches.

Read guideQuestions
Can I book a Mount Rainier campsite for tomorrow?+
No. Cougar Rock and Ohanapecosh both stop taking reservations a day before arrival, so a cancellation has to appear at least two days out to be usable.
Does White River take reservations?+
No. It is first-come, first-served, paid on arrival, so there is nothing to watch there. It usually opens in late June or early July.
How do I get a Mount Rainier campsite when everything is booked?+
Wait for a cancellation. They are common, but they rarely stay open long enough to find by checking manually, which is what Camp-Now watches for.
Does Camp-Now book the site for me?+
You always complete the checkout yourself. Camp-Now texts you the moment a matching site opens, with no Recreation.gov login needed. Link your account and it adds the site to your cart first, so it is held while you check out.
Is it free to start?+
Yes. Watching and alerts are free, with no card and no Recreation.gov login. If you turn on auto-booking, your first booked night is free too.
