Looking for a tent camping spot (tomorrow)

[grandpa]

My son and his buddy came up with a good (last minute) idea: "let's go camping tomorrow". So now, it's my job to figure out the "where" part. Where might you suggest within a couple hours of Olympia? They seem to prefer west rather than Mt Rainier (we're going up there next week). Tent and short hike seems to be the idea.

 

Thanks for whatever ideas you care to share...
