We have camped here repeatedly and find Unicoi to be a solid gateway to the North Georgia mountains. The campground is located off beautiful Smith Lake, but not situated on the water, except for the sewer sites that are located on a stream that flows to it. Sites are situated close to each other, so privacy is limited and they do need to be updated, but it is a beautiful setting and always shaded. Restrooms, except for the one in the tent area, are beginning to show wear, and there are two that are quite old. The park offers a wealth of weekly activities, including folk singing and Sunday church services.
Most of the reviews about Calhoun Falls are quite valid! I consider this to be a "modern" campground in that it was designed with larger RVs in mind; there is ample run off room on either side of the roads and almost all sites can easily handle the largest campers. All sites are paved with huge pads and privacy; the designers could have easily doubled the amount of sites. The comments about AT&T service are apt, but there is a corridor of reception near sites 62-64; other carriers seem to have better reception. Though bathrooms are showing some age, hosts do an excellent job of cleaning the pads when campers leave, which is especially nice in the autumn. There is the sound of trains in the distance off Lake Russell, but we actually enjoy this; it is by no means overly loud. We have camped here 20+ times and it is about as good as you can expect from state parks and is one of South Carolina's top ones.
