Great campground with only 2 less than ideal factors: 1) it is close to the main road through the park, so there is some occasional road noise. 2) the campsites are relatively close together. Otherwise, this is a great campground. It is mostly all shaded with lots of trees, birds and deer interact with the campers, convenient to the camp store with warm showers (.25 cents for 4.5 minutes) and close to the visitor center.
The good: This is a beautiful area with a lot of wildlife. We saw bear, wild turkey, deer and a coyote. The campground is very convenient to the camp store and Cades Cove. The not-so-good: the campground is very crowded and the campsites are close together. There are restrooms, but no showers. We had to drive about 10 miles into town and pay $5.00 each to shower at another campground.
Holly Bay is a great campground in the beautiful, but not very well known Daniel Boone National Forest. The campsites are semi-private with a fire ring, electricity, water (at each campsite), lantern pole, bathrooms and bath house. The campground is also on a lake with several good hiking trails around. I highly recommend it this campground!
