Map shows Chattanooga, TN. Times vary from Kingsport and Bristol.
Chattanooga pushes the day-trip limit but rewards early starters — the aquarium alone is a half-day, and the riverwalk connects downtown without a car once parked.
Pick **either** Lookout Mountain (Ruby Falls / Rock City) **or** aquarium depth unless you leave before sunrise.
Highlights
- Tennessee Aquarium & IMAX
- Tennessee Riverwalk & Walnut Street Bridge
- Ruby Falls or Rock City (Lookout Mountain)
