Take a look at the Long Beach, Wa. area. You can drive on the beach! If you go south from the Seaview, Wa. beach approach, you can drive South a couple miles to Beards Hollow. Some nice rocks and cliffs stop you form going any further. At low tide, you can see Starfish and more. You do not need an Discovery Pass to drive on the beach. If you have the time and a Discovery Pass, you can go to Ilwaco, Wa. Then follow signs to Cape Disappointment State Park. That is at the mouth of the Columbia River. You cannot drive on the beach there, but lots of great hiking and a rock jetty that goes out a ways into the ocean. Also Two different Lighthouses to check out. Also, a cool interpretive center, has the story of the Lewis and Clark Expedition.
One more area that is beautiful, go as far North on the Bay side of the Long Beach Peninsula, up past Oysterville, Wa. The little town is cool, follow signs to Leadbetter State Park. Again, fun place to hike! Hope this helps, Benz.
