If you prefer a campground with amenities over camping right ON the beach, Mora is the option you should choose for Rialto. Each site has a fire ring and table, and there are facilities within a short walk. There are also rubbish facilities and a dumping station. It's a peaceful place to camp just a mile or two down fro Rialto -- the main attraction in the area. If you aren't spending a night camping on the beach at Hole-in-the-wall, you'll want to grab a tide chart and make sure you hit the beach early enough to hike through it.

On your way to Mora you'll pass through Forks, WA -- this is one of the more decent size towns in the OP and you'll be able to restock supplies at Thriftway, grab a burger or pizza, and access wifi. You can also take a Twilight tour.
