Good old Chattanooga is chasing Knoxville's tail to become Tennesee's third most populous city and, arguably, the coolest in the entire state. Since 2013, Chattanooga's mayor, Andy Berke, has been using his platform to change the narrative of his hometown. Once devastated by the decline of its primary industry (steel), the city is confidently growing into its new identity - a fresh, progressive, citizen-focused place to settle down.

Millennials, in particular, are heading to Chattanooga to see what it's all about. With areas hip enough to rival Chicago's Wicker Park, a booming technology sector, and abundant gorgeous scenery, it's no wonder why Chattanooga is among the nation's top five up-and-coming cities. Head south to see what's on the must-do list during a visit to Chattanooga.

10 Fall In Love With Ruby Falls

For the most part, people head to waterfalls above ground, feeling the mist cascading over cliff tops and into pools of open water. Mystical Ruby Falls offers a different experience as the tallest, deepest underground waterfall in the United States. Visitors have to plunge 260 feet in a glass elevator and walk through a trail of breathtaking cave formations before reaching the roaring falls. The light show, a blend of blue, white, and red, illuminates the falls and enhances the enchanting views. Special tours offer guests the opportunity to explore by lantern light, paying tribute to how Leo Lambert first discovered the geological wonder in 1929.

9 Appreciate American Art

The Hunter Museum of American Art proves you don't have to be an artist to appreciate a masterpiece. The three buildings themselves are works of art, each telling a story of the museum's 70-year history. The outdoor sculpture garden primes guests for the pieces inside. The indoor collections narrate a history of American Art from the 1700s to the present day. The plentitude of media, including paintings, photography, and decorative arts, means there is something for everyone to appreciate. Rotating exhibitions highlight modern life in America and the unique ways our past has shaped our current reality.

8 Take A Whiskey Drink

When early settlers traveled west to the Americas, they brought with them their prized beverage - whiskey. Tennessee takes their whiskey-making very seriously, even setting forth a strict standard of legal guidelines for distilling and manufacturing.

Sip on a bit of history at Chattanooga's Experimental Whiskey Distillery, the first legal operation in the county in over a century. The owners went to the courts to make their dreams a reality, campaigning to change antiquated laws restricting distilling locations. From its microbrewing infancy to its fully matured operation, the distillery now offers an abundance of home-brewed whiskey drinks to sip on.
