We went after Labor Day, so the park was no where near as full as it is during the peak in Summer. Just a gorgeous spot to pitch up a tent. Beautiful view of the water, the Dam, the Mountains. The park and facilities are so well maintained!
Dam is only a 15 min car ride away and there is a laser light show every night during the season.
Only issue is people. You never know if you will end up surrounded by a good bunch of campers, or rowdy people that don't adhere to camp quite times. Luck of the draw.
