Access to Rex Hale was easy following the website instructions. Basically, you follow the signs through Cody to Yellowstone National Park via US 14, the park is right off US 14. There was no formal check-in. We had a reservation and that was noted on the post at our back-in site 9 with 50/30 AMP. There was confusion on our part whether we needed to get water before or after arriving based on several campground(CG) reviews. We called the ranger station the day prior who confirmed the water was on at the CG. Then we found out upon arrival that the sites as you come into the CG on the right side of the road up to site 12 have not only electric but also water! This was a recent addition and why water had been nonexistent or off in recent CG reviews. We were told there was a camp host but the host had actually already departed for the season. There was no cell signal nor OTA channels. There are about 30 sites with only sites 2, 3, 5, 6, 7, 9, 11, and 12 having electric and, now, water. The middle sites, the far CG end to the east and along the riverside of the CG have no utilities. There are water spigots periodically placed throughout the CG. There are several vault toilets but no showers. There is no dump station in the CG, but there is one in Buffalo Bill State Park near Cody. We were staying at an RV park in Cody and just dumped there. We were very impressed with this CG and really enjoyed our spacious site, the mountain views and the peacefulness of the place. We were here when they closed the CG for the season on 20 September and would definitely come back.
