Anderson Lake State Park in Washington, USA - map and visitor information

Research checked: 2026-10-23. Check linked official notices before travel.

Anderson Lake State Park is a day-use park near Chimacum on Washington's Olympic Peninsula. Forest trails and a freshwater marsh normally support walks, bike rides and horseback outings. The park is currently closed for construction. A separate toxic-algae restriction closes all water activities, so do not plan a lake visit until both notices permit it.

Forest trails around a protected lake

• Woodland routes: cedar, fir and alder surround trails used by hikers, cyclists and horseback riders when the park is open.
• Marsh habitat: freshwater wetlands add a different setting to the forest landscape.
• A day-use destination: this park does not provide overnight camping.

Fees, hours, and seasonal access

Keep people and pets away from the water

High lake-toxin levels can cause serious illness or death in people and pets. Do not recreate in or around the water while the restriction applies. Use the official park alerts to check both land and water access before making plans.

Respect the closed boundary

When visits resume, keep dogs leashed and follow the posted trail rules. Fires are prohibited at this park.

Plan a day visit after reopening

Anderson Lake is a day-use park, so arrange overnight camping elsewhere. Before bringing a group or horses, call the park contact to confirm reopening and the facilities available for your visit.

Use the Chimacum address

The park address is 1061 Anderson Lake Road, Chimacum, Washington 98325. Use that address to distinguish this site from other places named Anderson Lake.

Two other parks to consider by road

• Fort Townsend Historical State Park: south of Port Townsend, at 1370 Old Fort Townsend Road.
• Fort Flagler Historical State Park: at 10541 Flagler Road in Nordland. Check the chosen park's current access before setting out.

Save the trail outing for an open day

When the park reopens, its forest routes offer hiking, cycling and equestrian outings. Check the completed route layout and posted uses before choosing a trail, since entrance and trail work can change the approach.

Do not treat the park's usual allowance for nonmotorized boats and electric motors as current permission to launch. The toxin restriction takes priority over normal boating rules.

Check facilities after the entrance work

The park lists picnic tables, two vault toilets, equestrian trailer parking and hitching posts. These facilities are unavailable during the closure. The renovation includes changes to parking, restrooms and trail access; confirm which facilities have opened rather than assuming the planned work is complete.

About the lake and woodland

Washington State Parks manages Anderson Lake for day use. The mix of forest and freshwater wetland shapes the trail setting and helps explain why both shoreline protection and trail rules matter here.

Forest and freshwater-marsh habitat

Cedar, fir and alder form the woodland around the freshwater marsh. Observe the habitat from permitted routes after reopening.
