Fun hike! Look carefully for the trail posts. Maybe not the most intuitive, but pretty well marked. There’s a section through dense brush that’s formed as a sort of tunnel. Reminds me of that scene in Star Wars with Luke and Vader in the forest. Follow the foot tracks in the dunes if you feel lost. Well worth it once you reach the beach.
Northwest forest pass or a 5$ daily use fee will allow you to park. From there cross the bridge and walk a little less than a mile to encounter the first big dune. No need to travel further if your party can't make it to the beach as these first few dunes are fantastic enough and will easily chew up an hour climbing them. Big view from the top of the first one as you exit the forest. Do it! If you do wanna walk to the beach, just follow the poles with the blue tops. I went about half way before my party puttered out. (A bit bummed by that) Signage say it is 6 miles round trip and about 4 hours. There is confusion about dogs and the endangered bird nests. From what I can tell the restrictions only apply as you get close to the beach. I'm not positive about this and the information available and signage doesn't all tell the same story. But beware, low to ground and the tops of dunes (where a dog would be) the wind blowing sand seems it might irritate them...so maybe stay down below. UPDATE: we returned and pushed to the beach. It took 65 minutes there with steady walking, and a little less on the way back. The trees you can see at a distance about halfway across the dunes are indeed just about at the end. They have a clear path and boardwalk thru them that goes for nearly a couple hundred yards.
Such a great hike! Only saw a couple other people on the trail and had the beach completely to ourselves.
Short hike out to the Dunes and great view once you hike up to the top of the first large dune.
Perfect place to go hiking, sand dune sledding or just admiring the vastness of the dunes. Combined with camping nearby, perfect adventure outing.
