Gatlinburg has four distinct seasons, as mentioned above. In spring and fall, make sure to bring plenty of layers and rain gear, as the weather is unpredictable and may not match the forecast from the week before.
In winter, bring lots of cold-weather gear. While the average lows in town are right around freezing, the temps up in the mountains can drop much more. If you’re a hiker, don’t get caught out in the snow without warm gear, food, water, and a communication device.
In summer, remember your bug spray, poison ivy wash, and EpiPen if that applies to you. There are tons of mosquitoes, ticks, bees, and yellow jackets in the park.
