What happens when you set this watch
We track every fare from your airport into Knoxville or Asheville for May 25 to June 20, 2027, round trips of 2 to 4 nights, across every airline. The moment one drops, you get one email with the dates, the price and a link to book. Free, and you can stop any time.
Know before you go
- Enter the park lottery in late April, only a few thousand passes are drawn
- Without a pass, nearby Cades Cove and Congaree in South Carolina have their own synchronous displays
- Knoxville airport is about an hour from Elkmont via Gatlinburg; the Sugarlands shuttle is the only way in on event nights.
