We love Cape Disappointment State Park. Our go-to destination is Waikiki beach. It's a bit more secluded from the wind and the waves aren't as rough as the main beaches so it's MUCH better for families. The Lewis & Clark museum overlooks the beach and is a great stop while you're there. If you're up for our trifecta it's visiting Waikiki beach, hitting the museum, and then hiking to the lighthouse. It makes for a great day and gets the kids nice and tired. A heads-up for those camping at the park, though. It's windy, windy, windy. The camping areas are awesome, but a lot of the people we talked with weren't prepared for the constant wind. They are in an area with very little protection from the ocean winds. We like Waikiki beach and the backside of the park (museum and hike) partially because of the wind protection there. Still, it's an amazing place and a must visit if you're in the area.
