Just got back from Pigeon Forge like a week and a half ago.
Anakeesta was fantastic highly recommend as was the new skybridge. Ripleys attractions are a skip unless you have little kids. Gatlins is a place often overlooked but highly recommend checking out one of their escape games and the rope course.
If you want a real thrill check out FoxFire Mountain and do their zip line tour. They offer two, the tree top and the Goliath. The Goliath is not for the faint of heart with the main line being 475 ft off the ground while hitting a top speed of 70mph.
I’ve done all the mountain coasters and my favorite is the one right across the street from Dollywood, and if you bring your Dollywood ticket you get a discount on your ride.
Finally food, if you like BBQ you have to try Bennett’s they have two locations in the area. Also the Pancake Pantry is fantastic just be advised it’s cash only there. Skip Paula Dean, Red Rooster, and Lumberjacks for breakfast.
