What follows is an excerpt from the full campground report on my blog. For the full report with more photos click here
Hot Springs National Park is both surrounded by the town of Hot Springs as well as surrounding part of the town. This is in Arkansas, by the way. Gulpha Gorge Campground within the park is something of an oasis from the nearby community. At the same time, route 70B (Grand Avenue) skirts the SE edge of the campground and it's busy with cars passing by most of the day. Site 21 where I camped was a little further from the road than most other sites but still, at maybe 200' from it one could see and hear passing traffic. I do not recall noticing traffic noise in my rig at night. There probably isn't much traffic then.
This is, from all appearances, a popular campground. Pretty much all the sites with hookups were taken midweek when I arrived. Just the day before I showed up I was at Cedar Lake in OK where most sites at two of the three campgrounds there were vacant. Gulpha Gorge Campground felt crowded. It's small in size and it was full in the section with hookups.
