Getting a campsite at Centennial Trail
How do I get a campsite at Centennial Trail when it's sold out?
Cancellations happen constantly — the trick is being first to know. Set an alert for your dates and we'll watch Centennial Trail on Washington State Parks around the clock, then notify you the moment a site opens. Alerts run on a Pro subscription ($9.99/mo, cancel anytime).
When do campsites usually open up at Centennial Trail?
Whenever someone cancels. Most reservation systems refund less the closer you get to arrival, so cancellations cluster in the days before a stay — but the openings themselves are unpredictable, which is exactly why watching for them beats refreshing the page.
How fast do cancelled sites get rebooked at Centennial Trail?
At high-demand Washington parks a cancelled summer-weekend site is often rebooked within minutes — sometimes under a minute. Being notified the instant it opens, with your Washington State Parks login and payment already saved, is the difference between getting in and missing it.
Where do I book a campsite at Centennial Trail?
Reservations for Centennial Trail are made on Washington State Parks, the official booking system for Washington State Parks. GetParkAlerts is independent — we tell you when a site opens; you book it directly on the official site.
Does GetParkAlerts reserve the site for me?
No — we never hold or book sites. We tell you the second one opens so YOU can book it on Washington State Parks before anyone else. Booking always happens on the official state system.
