What Our Guests Have To Say

Lots of Fun!

Amazingly beautiful! Heavily wooded, trails, cabins, tent camping, right in the big river with a small beach… kids would love it! The tent camping area is paved and has a playground, so it’s perfect to bring the kids bikes. Such a beautiful and large park! Lots of fun for all ages.

We'll be back again!

Washington State Park was a lot of fun. We camped for a few days. The park host was great and provided recycling bags. The shower house is great, cleaned everyday, and very close to the electric sites! We enjoyed the petroglyphs, overlook, trails, playground, swimming pool, and park store. We will definitely be back again!
