Highway 20, Northen Washington State

You won't find any full hookup in the Nat Park. As to either side of the park, there are good references for campgrounds at RV Park Reviews, and Allstays sites. A great (IMO!!) is Moon Pacific Northwest Camping compiled by Tom Stienstra. Mucho info, doesn't list every darn campsite or campground, but does a very good job. Includes fees (up to date??), directions, websites, and max lengths of rvs. Great for a large rig!! Hope this helps!.

We are going up there in May or June (open at this time!) and are spending time researching many sites and dispersed camping possibilities!!
