Washington State Parks’ online reservation system will be down from Wednesday, Jan. 8, through Tuesday, Jan. 15, as the agency puts the finishing touches on a new and improved system to be launched Jan. 16, according to a state parks news release.

During that transition week, all Washington state park campsites, day-use shelters and accommodations will be first come, first served and payable at the park by cash only.

On Monday, Jan. 14, the system is scheduled to open for existing customers to update their accounts, including changing passwords. It will not accept new reservations. On Jan. 16, all customers can use the website www.parks.state.wa.us to reserve campsites, cabins, yurts, some vacation homes, shelters and group camps up to nine months out.

The new system will add 90 campsites, 38 cabins, seven day-use facilities and six group camps. It will allow visitors to book multiple parks and sites in one online session, see retreat center availability, and expedite the check-in process plus more. The enhancements also make the system mobile-friendly and easily navigable
