We read about this hike in Craig Romano's book, "Day Hiking Olympic Peninsula". To reach the TH go west from Hoquiam on SR 109 for 21 miles to Coplalis Beach turning left at the Green Lantern Tavern onto Benner Road. The park entrance is 0.2 miles. A Discovery Pass is required. Round trip is 4 miles, but we probably walked only 3 plus miles as the day was wet and windy. From the TH it is a .75 mile walk through grass covered dunes to the ocean. Where Conner Creek goes into the ocean one can usually access the ocean beach. However the trail appeared to have eroded away so we continued along the wide sometimes water-covered trail through the dunes for about another 1/2 mile before the trail turned to the beach. There were hundreds of shore birds along the edge of the ocean. The rain was blowing side ways so we were at the beach a very short time so never reached the Copalis River. The vegetation on the dunes was beautiful!

Hiked this in rainy, cloudy, and cold weather. Other than the wet weather, this was quite enjoyable! I'm used to hiking in forest, mountain type trails in Issaquah and North Bend so this was a nice change of scenery.

Finding the trailhead was a bit confusing. It is just past the large covered picnic tables in the park area. It starts out through some grass, then through a little bit of brush. Once you hit the wooden path, you are greeted with a gorgeous view of the Pacific!

The trail follows the coast northward and splits off to many smaller trails through the grass. Most of what you see are large grass fields alongside the sand. There is virtually no elevation gain at all.

We would have followed the main trail a bit more, but there was too much water on it. We turned back after about 1.5mi into it and enjoyed navigating the smaller trails through the grass. Dogs would love this easy little hike!
