Grandy Lake Campground

Great location, right on the water. I would give this the highest of stars if there was better access to the water from the campsite. A lot of blackberry and plant overgrowth , but there are trails through it to the water from most campsites. But all-in-all? A great place to stay and relax. And, as mentioned above, big rigs to the left small rigs and tents to the right.
Have 2 bars of Verizon without my signal booster, it's a little slow, but definitely doable. Photos above do well justice, no need to add my own.

This campground offers dry camping only, and campsites are on grass. I would give it a 3 1/2 rating, but that is not available, it's a good value for $7 a night. There are only a couple of sites that accommodate big rigs, these are to the left as you enter the park. The road to the right is really tight and none of the campsites are large enough for a big rig.

There are trash cans and port-a-potties, but no other facilities. Several campsites are right on the river with access to the shore, although it is pretty overgrown. This seems like a popular campground for fishing.

The closest town was Concrete, but we did not go there. We thought that the campground would be convenient to North Cascades National Park, but it was a bit of a drive.

Overall a quiet and pleasant place.
