Visit Knoxville, TN

Market Square is the place to be in downtown Knoxville! Here you’ll find outdoor concerts, quaint restaurants, and local breweries, all within walking distance. Stretching away from the Market Square is Knoxville’s Urban Wilderness, spanning 1,000 acres of parks, 50 miles of hiking and biking trails, and civil war sites.

Head to the University of Tennessee campus to visit the McClung Museum of Natural History & Culture. You’ll find exhibits that showcase historic Tennessee as well as cultural artifacts from across the world. The Knoxville Museum of Art houses the permanent exhibition “Higher Ground: A Century of the Visual Arts in East Tennessee”, which celebrates East Tennessee culture. Other exhibits include “Facets of Modern and Contemporary Glass” that holds 20th and 21st century glass art pieces, as well as mini historic interiors of the museum’s early history. 

The Great Smoky Mountains are an outdoor enthusiast’s ultimate playground. This national park is only an hour away, making it a gorgeous day trip. There are over 800 miles of trails to hike, over 75 historic sites to see, and scenic overlooks everywhere you go. The park can be enjoyed in any season, with lush green foliage in the summer, wildflowers in spring, rainbows of colored leaves in the fall, and even more vistas with a lack of leaves in the winter. There’s a reason it’s America’s most visited national park!

You’ll find Ijam’s Nature Center inside the Knoxville Urban Wilderness. It houses a wildlife sanctuary, miles of trails for hiking and mountain biking, a museum, and a quarry lake for fishing or kayaking. The best part is, it’s just minutes from downtown!

Going to Zoo Knoxville is a great way to spend an afternoon while supporting endangered animal populations. They work together with other accredited zoos across the country to maintain diverse populations of animal species threatened by extinction. Here you’ll see unique animals like Malayan Tigers, Red Pandas, and Red Wolves.
