Hiking recommendation near Northshore

Hello! My significant other and I are traveling to Chattanooga for the first time and looking for hiking recommendations. The Airbnb we are staying at is in Northshore about a mile from the aquarium. We are driving in from a pitstop in Nashville Saturday morning and don't check in until 3 pm.

We are looking for a scenic mountain hike that is 5 miles or less. Thanks in advance!
