Griffiths-Priday Ocean State Park is a 364-acre marine park with 8,316 feet of saltwater shoreline on the Pacific Ocean and 9,950 feet of freshwater shoreline on the Copalis River. The park extends from the beach through low dunes to the river, then north to the river's mouth. The Copalis Spit natural area, a designated wildlife refuge, is also part of the park.

Park at the Giffiths Priday Ocean State Park parking lot. You will need a Discovery Pass or pay $10 for the day. Walk towards the ocean. At the sign that says no beach access make a right into the brush. You will be walking along the Copalis river spit at this point. Watch your step near the high bank along the river. There have been washouts. Continue to weave along the shoreline until you reach a low bank area where you can walk onto the beach. We continued north along the beach until the tide stopped us from walking any farther. We only saw two other people along this route. Our dog was off leash the whole time with no issues. Lots of beachcombing to do if you are interested.
