The city, which has a downtown elevation of approximately 680 feet (210 m), lies at the transition between the ridge-and-valley portion of the Appalachian Mountains and the Cumberland Plateau. The city is therefore surrounded by various mountains and ridges. The official nickname for Chattanooga is the "Scenic City." Several unofficial nicknames include "River City", "Nooga", "Chattown", and "Gig City", demonstrating that Chattanooga currently has the fastest internet service in the Western Hemisphere.[4][5]

Chattanooga is internationally known for the 1941 gold record song "Chattanooga Choo Choo", which was popularised by Glenn Miller and his orchestra.

Chattanooga is home to the University of Tennessee at Chattanooga (UTC) and Chattanooga State Community College.

Since 1990, Chattanooga has been recognized as a Tree City USA community.[6]

We love walking to the library, farmers market, restaurants, park, school, or just walking around downtown to be walking. The new grocery, Enzos on Main is gonna be a huge plus too and it opens in March.

Being able to walk to do errands. Bank/post office/gym/STYLEbar and such and not having to pay to park while doing them. I enjoy walking to dinner and a movie or one of the numerous downtown events.

Living in the River Gorge is awesome. It is great place for land and water recreation. It only takes 10-12 minutes to be in the heart of downtown.
