Sherwood Forest is perfectly located just 1 1/2 miles from the Parkway to give you the isolation and quiet you want while being close to all the action. There are tons of activates within a few miles of the resort - Dollywood, restaurants, outlet mall shopping, zip-lining, go-carts, putt-putt golf, etc. It also sits right on the edge of the park allowing easy access. Gatlinburg is also a quick 5 miles away so you can go there for a day trip.
Smoky Mountain national park is a short 5 mile drive.
The Smoky Mountains are an amazing place - hiking trails, drive-to overlooks, biking, and animals galore. In recognition of the park's unique natural resources, the United Nations has designated Great Smoky Mountains National Park as an International Biosphere Reserve.
I am sure you will fall in love with its beauty the same way I did.
