We stayed at Nk Mip Campground which boasted a grocery store, playground, dog beach and indoor pool. I loved that we were right on the lake, the boys were in the water every time the sun came out. Open campfires are not allowed though so we bought a propane fueled one. And our site was a bit far from the playground and pool so I would book one closer to all of the action next time.
We toured around the area a bit when it was raining. The kids watched a movie on the dvd player while we took in the sights.
