My family of five camped three nights at Elkmont the last week of March 2024. High was in the 50's and 60's and low in the 30's. It was windy and cold at nights. I did a ton of research attempting to book a"private" site at this campground--but now I'll share what I have learned-- there are none! We had site A-7, which is"walk-in", but the walk is incredibly short and not far from your car. All of the campsites are extremely close together, and there is no brush to divide them. That said, the campsite is gorgeous and I do recommend it. Despite having no visual privacy, the sound of the rushing water masks all the sounds of talking, etc. and I slept great with the rushing water. Considering the walk-in sites are no more private than any other, I think my highest recommendation would be the B sites. Otherwise try to book any site along the river. 

The bathrooms were adequate--sinks and toilets and cleaned daily (no showers). We did one of our hikes from our site--the Little River Trail to Cucumber Gap at it was beautiful. While the technical distance of that loop is 5 and a half miles, it was 7 miles total from our site. I recommend doing Little River Trail first, as it is a gradual uphill on a gravel road. While the wide road is not ideal, it is along the beautiful river. Cucumber Gap trail is single track with some nice views. The final portion of that loop, Jakes Creek Trail to the Elkmont Historic District is STEEP--so I was glad we were going down, not up.
