This is by far the nicest campground in North Cascades National Park that one can drive to.  If you are lucky to be able to reserve beach side spots on Diablo Lake you will also have lots of privacy and incredible views of this amazing turquoise blue lake and maybe even your own water access/beach.  If not, the dock and beach are only a few steps away. Bathrooms are pretty basic, no showers. Cell reception is non-existent.  Amazing access to the lake and incredible hikes from your campsite!
