Washington's oldest state park is about to get its most significant infrastructure upgrade in years. Larrabee State Park, located along Chuckanut Bay south of Bellingham, will close its campground on September 15 for a water line replacement project that will run through June 15, 2027. Crews will replace aging water lines throughout the park, including pipes that may be nearly as old as the park itself, which was established in 1915 and is now 111 years old.
Washington State Parks says the project will improve water distribution throughout the facility, reduce the maintenance emergencies that have plagued the aging system, and improve the overall visitor experience once the work is complete. The project is expected to take roughly nine months, spanning fall, winter, and spring before a summer 2027 reopening of the campground.
What Stays Open During Construction
Not all of Larrabee will be off-limits during the construction period. According to park officials, several key facilities will remain accessible. The boat launch will stay open, as will Cleator Road, Clayton Beach, and the Lost Lake parking lot. These are among the most heavily used non-camping access points in the park, and their continued availability means hikers, kayakers, and day visitors will still be able to reach many of Larrabee's most popular spots throughout the project.
Day-use facilities may also be available at certain times during construction, though the park is warning visitors to expect changing conditions. What is open one week may be temporarily off-limits the next as crews move through different sections of the water system. Anyone planning a specific trip to Larrabee during the construction window is strongly encouraged to contact the park directly for the most current access information before heading out.
The campground itself, which includes tent sites, utility hookup sites for RVs, and the group camp area, will be fully closed for the duration. Reservations made through the Washington State Parks reservation system for dates after September 15 and before June 15, 2027, will need to be canceled or modified. Campers who had planned fall or spring trips to Larrabee should check their reservations and start looking at alternative sites in the region.
Why This Work Is Necessary
Larrabee State Park's water infrastructure challenge is common across Washington's older state parks. Many parks in the system were developed during the mid-twentieth century with water lines that have now exceeded their intended service life by decades. At Larrabee, some pipes may date back close to the park's founding era, meaning the system has been patched and maintained rather than systematically replaced for over a century of operation.
Aging water lines in park campgrounds create recurring problems: unexpected breaks that flood campsites, service interruptions that force emergency closures, and water pressure problems that affect restroom facilities and potable water access. Each emergency repair costs money and staff time that could otherwise go toward other park improvements. A comprehensive replacement addresses the root cause rather than the symptoms.
Washington State Parks operates Larrabee as part of its statewide system of over 100 parks. Larrabee is particularly significant as the first land donated to the state for the parks system, a gift made in 1915 by the family of Charles Xavier Larrabee. The park covers roughly 2,683 acres stretching from saltwater beaches along Chuckanut Bay up into the Chuckanut Mountains, encompassing some of the most popular hiking and marine access in the Bellingham area.
Planning Around the Closure
For Whatcom County residents and visitors who use Larrabee regularly, September 15 is the key date to mark on the calendar. The campground closes that Monday, meaning the busy fall foliage season will see the campground offline for what is typically one of the more pleasant camping windows of the year in the Pacific Northwest.
Nearby alternatives for overnight camping include Birch Bay State Park to the north, Rasar State Park in the Skagit Valley to the south, and several Whatcom County parks that offer camping. The North Cascades also offer dispersed camping and campground options for those willing to drive east on Highway 20. Bay and water-access camping similar to Larrabee's setting is more limited in the region, making the closure a meaningful disruption for fans of Puget Sound saltwater camping.
For updates on what is accessible at Larrabee during construction, contact the park directly through the Washington State Parks website or by phone. The parks system also posts alerts and reservation changes on its online booking platform.
