A salty experience
If you want an easy trip to the coast with some key amenities nearby and plenty if beach access, the Grayland will treat you well, if it doesn't rain. There's plenty of access to the beach when it's open to razor clamming or you can even give it a go at fishing for surf perch. Plus there always surfing and find relic shells.
You gave grate full meal deal with camping facilities including a shower to rinse off the salt. The walk in campsites are a good treat if you want a little privacy or have a big group during the offseason.
