Nice park run by NPS but due to economy the marina closed down and the Overton Beach marina closed down completely so there isn't much here anymore and it is pretty much out of the way. A better bet is Callville Bay about 20 miles down the road and still on the lake. Big marina there. We camped here in a Fifth Wheel.
I didn't follow my own rule - never book an RV Park without a decent review on this website and pictures of the sites on the camp website. I was drawn in by a professional looking website and the "Seven Crown Resorts" name. This place was AWFUL!! The "resort" is 14 road miles (over an hour drive) from Hwy 167. It isn't their fault, but they should have mentioned (in 2 different phone conversations) that the road is being resurfaced. We drove over a mile in the dark on a gravel construction road. This place is in the middle of nowhere! When we finally arrived, we found the "resort" had nothing but a bathroom/shower/laundry building. There were no other facilities. We had to call from a phone on the wall to check-in at the nearby hotel. There were no site maps, etc. I drove down to the hotel and realized that Lake Mead is over a mile away. The staff at the hotel office told me that the lake had retreated because of the drought, but clearly the lake has never been anywhere near the RV park. Their website says "Our lakeside hotel and RV Park ..." but this is obviously misleading. The hotel staff gave me a poorly photocopied map of the site and showed me our site was right next to the bathrooms. I asked to be moved somewhere else and they had no idea which sites were available. At this point it was late at night and I just wanted to hookup, turn on the AC, and sleep. We parked in a different site for the night. Apparently the RV park is also where local employees live. There were some big Class A rigs in the park, I assume they had boats and were spending their time on the lake. The next morning I called the office and told them we were leaving rather than staying two nights. They agreed not to charge us for anything. We camped here in a Motorhome.
