Nothing to see here.....
I24 goes right through Jasper, Tn and crosses an epically picturesque section of Nickajack Lake. Nickajack dam is within a few minutes of the I24 Jasper exit and Shellmound Campground is located adjacent.
Shellmound is "privately" managed and can not be reserved through RecGov.
The RV section is crowded with no privacy, but maintained and clean. There is a playground area at the front and it is separated from the day use area.
The primitive campground is located behind the RV Campground and seperated by trees from the RV's. There are a few spots within the trees to camp and a "parking" area. The rest of the primitive area is in a large field with an awesome view of the lake, pick a spot. So depending on when you arrive and how crowded the area is you may not get a tree or next to the lake:) there are picnic tables and fire rings. I didn't inquire as to their maximum capacity.
The day use area is very nice, manicured with a swimming area, dock and boat ramp. The water was surprisingly clear and COLD!
I noticed a sign for Little Cedar Mountain Trail on the way out, but did not have the opportunity to check it out. Maybe next time.
