FIRSTLY, do NOT take Sykes Creek Road or May Creek Road to access this campground. Google Maps will try to take you on the shortest (mileage) route. Both of those roads are treacherous and take more than twice as long as predicted by Google Maps. Coming from Wimer, stay on Evans Creek Road until you see the sign for Elderberry Flats, then turn left and continue about 9 miles to the entrance. It's paved the entire way.

We stayed at this campground the weekend after Labor Day 2022. There are 11 spaces: two were occupied but abandoned, two appeared to be occupied by folks living there (beyond the 14 day mark), and three were being used by campers (including ours). At least five of the campsites are next to the creek with easy access for wading, etc (some portions appear to have small swimming holes). There are walking paths (unpaved) that can also be accessed by OHVs. There is a pit toilet in the campground plus another one in the day use area. Your best bet is to bring your own toilet facilities; the pit toilet in the campground was "well-used".
The site we used was clean of debris, very spacious; more than enough space for our two tents, two easy-ups, corn hole game, and four vehicles in the driveway (including our Scamp) with still a lot of space. The provided picnic table was sturdy, coated metal mesh and offered a handicap space at each end. The fire ring was a metal barrel with a sturdy grate.
The first three days there was no sign of wildlife…no squirrels or chipmunks, no birds, etc. It was eerie. By the fourth and fifth days, the wind picked up and the birds and critters showed themselves. We didn't seem to have any issue with mosquitos although, when eating, there were a few bothersome flies and bees and some gnats.

There are several options for boon-docking along West Fork Evans Creek Road but in the camp ground there were regular drive-throughs by some authority who were aware of the abandoned camps and the folks over staying the 14 day limit. I say this because a few locals rolled their eyes when I said we were going to Elderberry Flats and gave warnings that we may encounter some less desirables. There were some questionable "campers and campsites" but we didn't have any trouble at all.
