We had a thrilling ride with our knowledgeable-nature loving guide, Joey. Most "Gatlinburg" rafting companies operate on the Pigeon River which is about 25 miles east of Gatlinburg and on scheduled dam control. This means that they get 4 days a week of constant/controlled water pressure, unless there is a drought. Their seasons are mostly late April-early Sept. We had a great time with a very physically fit group of teens, but older, not-so-in-shape people and young children were also enjoying the river.
FYI-There really is no nice place to eat when you return to camp, but the area is beautiful--PACK FOOD, DRINKS & DRY CLOTHES, then stop at one of the mountain overlooks on 339/Foothills parkway to eat.
