OLYMPIA – Mystery Bay State Park on Marrowstone Island will close from July 14 through August 20 for major repairs to its pier.
The park will remain open for boat-in traffic only. Boaters may not come on land while the 18-acre park is closed for safety due to the use of heavy equipment throughout construction. Boaters can use the dock and the two open mooring buoys by self-registering at the dock pay station or using the mooring buoy call-in program to register by phone from their vessel.
The Mystery Bay pier closed last spring due to structural concerns. During construction, crews will replace failing supports with new steel pile posts and pile caps.
We appreciate your patience as we work to make the pier safe for your next visit.
