instruction: When is the best time of year to visit the Smoky Mountains?
response: The Smoky Mountains are open and accessible year around.  One can visit the Smokies during each of the 4 different seasons and have a completely different experience in each.  Colder months, such as December through early March, are great if you want to explore when it's less crowded, but be prepared for certain higher elevation trails and roadways to be closed due to ice and snow.  Summer months are great for morning hikes and hikes at higher elevations as the temperatures are moderately warm and comfortable, but be prepared for larger crowds, as this is the busiest time of year around the park.  In October, the Smokies are full of red, orange, and yellow leaves changing colors before dropping for the Winter.  This is one of the more beautiful times of year in the Smokies, but also a very busy time as visitors flock to the park to see all the colors.  Spring break is also a great time of year to visit the Smoky Mountains, as the weather is cool for long hikes, the bears are just starting to come out with their cubs, and the crowds are less than what you'd see during the summer.
