Even though you can visit the state at any time, the best time to visit Tennessee depends on what the goal of your vacation is. March through May and September through November are considered to be the most pleasant months with balmy days, cool nights, and a reasonable level of humidity. Nothing beats glancing at blooming flowers in spring and enjoying spectacular foliage in fall. Views from Clingman's Dome are amazing throughout both of these seasons. The time between June and August is considered to be the busiest. Escape the heat and choose Fall Creek Falls and Machine Falls to cool down a little and relax. Tourist flow subsides by the time winter approaches—high time to hit the Little River Road to explore the Smokies at their best.
