Fall in Missouri means long-sleeved shirts, blue jeans, evenings around a fire and enjoying cooler temperatures and beautiful colors with your favorite traveling companions.
The reasons to travel to Missouri in the fall are myriad, from festivals and foliage, to sporting events and sightseeing.
Camping is another popular fall activity in Missouri. By late September and early October, the humid days of summer generally have given way to the crisp air of autumn, meaning daytime temperatures are just about ideal (60s-70s) while nights are chilly (30s and 40s), but great for sitting beside a fire.
Of course, this is Missouri, so temperatures can jump up to 90 just about any time, while a sudden cold snap might bring frost. You just have to be prepared.
