FAQs about flying to Knoxville

Knoxville climate

Situated in close proximity to the Tennessee River, Knoxville sits comfortably in the broad valley of the Cumberland and Great Smoky Mountains. In the cold season, winter air rushes in, chilling things a bit, and in the summer, hot winds from the west and south sweep through the area, sometimes adding a few evening thunderstorms to the mix. Precipitation comes at its highest point during the winter and early spring, when snow and rain occasionally make appearances. January temperatures usually drop to below 0, and July temperatures skyrocket to the low and mid-20s. 

Getting around Knoxville

While there’s not a plethora of transportation options when you travel to Knoxville, the city itself is structured so that the closer you are to the centre, the easier it is to travel around on foot. Renting a car is a popular choice, and the roads are typically simple to navigate. Taxis are hailed on the street, but it’s easier if you call ahead for one. Otherwise, no bus services are offered – but you can take advantage of the railroads if you prefer to expand your Knoxville travel further.

  • When is the best time to fly to Knoxville?

    Summer is the best time to book a cheap flight to Knoxville, when the air is full of country music, and the temperatures rise just enough to soak in the sun. Peak Season: The best time to visit Knoxville is when the sun is shining and the city comes alive. Spring and summer set the perfect atmosphere for outdoor concerts, al fresco dining, and exploring the city on foot, so visit when you can get the most out of your travel to Knoxville. Off-peak Season: Although winter usually attracts fewer travellers than the rest of the year, you’re likely to find deals on hotels, and cheap flights to Knoxville if you come here in the cooler season.

  • What is good to know if travelling to Knoxville?

    Market Square: A feeding ground for all five senses, Market Square has the hustle and bustle of the city down pat. When you visit Knoxville, definitely put this at the top of your agenda. Teeming with restaurants, shops, and concert halls, culture and entertainment are bridged here, and enjoyed by the happy crowds of people that can do enjoy a cocktail, savour a gourmet meal, or rock out to their favourite bands all on the same block. A perfect place to enjoy the weather, Market Square is usually packed in the summer, especially for the free outdoor concert series. Knoxville Zoo: While you can’t take one of these fuzzy little creatures home, you can surely enjoy their company when you visit the Knoxville Zoo. See red pandas in their natural habitat exhibits, or watch otters swim around in graceful formations in the water. Although sometimes criticized for being situated a little too close to the road (you can see cars through some of the exhibits), the baby rhinos don’t seem to mind, and neither do the happy kids that run through here. Knoxville Museum of Art: If you’re craving a little artistic culture when you travel to Knoxville, look no further than the Knoxville Museum of Art, which is the perfect place to go on a rainy day. Situated on World’s Fair Park Drive, the museum hosts 12 temporary exhibitions a year (once a month) and has wonderful permanent collections that focus on postmodern works. For anyone interested in art, both local and national, this is the place to see it. Boom’s Day: If you’re planning your visit around Labour Day on 1st September, then you will be able to catch one of the biggest events of the year called Boom’s Day. Held on the waterfront in honour of Labour Day, huge, bright fireworks are held on the waterfront with an enormous musical soundtrack played from a live band. More than 400,000 spectators come every year and enjoy the aesthetic display. Once filmed by national Geographic for its special features, this night filmed with live entertainment is surely one for the books.
