Gatlinburg gay
There might be some in Knoxville. However Pigeon Forge and Gatlinburg are gay friendly. I have seen a lot of same sex couples in the area and they didn't have any problems that I know of. Go have fun and enjoy your trip and The Great Smoky Mountains.
From the hip and happening "Drag Queen Manor" to the quiet and quaint "Rainbow Ridge," you'll find a range of gay guesthouses in Gatlinburg to fit your fancy. And remember, booking through misterb&b is a fabulous way to meet locals and find a unique LGBTQ+ stay.
