Introduction of Twanoh State Park

Twanoh State Park is a beautiful park on the Hood Canal. This park has enough space to spend an entire day exploring; in addition to the trail, there is a beautiful beach and creek. At low tide, sea life is abundant, and it’s a great place to see salmon spawning in the fall. This is 2.3 miles long with half an uphill and half a downhill, so even though it is family-paced, a carrier will most likely be required for the toddler’s legs to rest. The trail ascends the hillside alongside the creek, passing by numerous large trees and wild rhododendrons.

Once at the top, our group enjoys playing in the grassy open field known as the “group camp.” There is a steep trail back down, but we usually just take the service road. The trail “offers a variety of gentle forested walks alongside or near babbling Twanoh Creek,” according to the WTA. Numerous benches along the way provide ample opportunity to rest or simply sit and enjoy the forest; mileage markers will help you keep track of your distance.” Cross the highway (there are marked crosswalks) after hiking to explore the beach and play on the small playground.

Twanoh State Park Camping

There are 25 tent spaces, 22 full hookup spaces, six restrooms, and one shower at the park. The maximum length of the site is 35 feet (may have limited availability). It is not permitted to gather firewood, but packaged firewood can be purchased from the campground host or local stores. All campsites are available on a first-come, first-served basis.

The park has a group camp that can house up to 50 people. There is a picnic shelter, a water tap, and a vault toilet. The dirt road leading up to the group camp is steep and winding, so vehicles other than RVs are not permitted. The rental fee is determined by the size of the group.

Check-in begins at 2:30 p.m. and ends at 1 p.m. Quiet hours are between 10 p.m. and 6:30 a.m. Engine-powered electric generators may only be used between the hours of 8 a.m. and 9 p.m. Length of stay: During the summer, you may stay in any one park for up to ten consecutive days; between Oct. 1 and March 31, the stay limit is increased to 20 days.
