Some of the best U.S. national parks for camping are in Washington state, including Olympic National Park — this national park on a beach offers about 900 campsites across 15 different campgrounds. But at Washington’s state parks, campsites have always been first-come, first-served unless you reserved them at least a day in advance. Now, snagging a last-minute campsite just got easier, as Washington has expanded same-day campsite reservations.
As of March 2025, the Washington State Parks and Recreation Commission changed its reservation system to allow same-day booking online or by phone until 2PM on arrival day. This move came after a successful pilot program launched in 2023 at Cape Disappointment, Deception Pass, and Millersylvania state parks and expanded to 24 more parks in 2024. With over 7,000 same-day reservations booked since the test began, it became clear that allowing last-minute bookings helps both travelers and parks by keeping campsites filled while giving campers more flexibility.
So, if you’ve ever had a spontaneous urge to escape into nature at one of Washington’s many beautiful state parks, you can rest assured that you won’t have to roll the dice and hope there are still spots left if you arrive later in the day.
