Hit the Trails this Fall
September 22, 2026
“The best season to get outside.”
——-
Fall officially arrives in the United States with the autumnal equinox, which in 2026 occurs on September 22—making today the first day of astronomical fall. For hikers, that means cooler temperatures, changing leaves and, in many places, a more comfortable time to get outdoors. And Americans could probably use the encouragement: according to the CDC’s latest National Health Interview Survey data, only 47.2% of U.S. adults met the federal aerobic-activity guideline in 2024. That guideline calls for at least 150 minutes of moderate-intensity aerobic activity each week, and a brisk hike can certainly help accumulate those minutes.
The benefits go well beyond burning a few calories. According to the CDC, regular physical activity can improve sleep, reduce feelings of anxiety, strengthen bones, improve balance and lower the risk of heart disease, stroke and type 2 diabetes. Of course, fall hiking requires a little common sense. The National Park Service recommends checking the weather and trail conditions, wearing appropriate footwear, carrying water and food, packing extra layers and bringing a flashlight or headlamp. With daylight getting shorter, it’s also smart to establish a turnaround time so you’re not unexpectedly finishing your hike in the dark.
I vividly remember hiking to the bottom of the Grand Canyon one fall with friends. The crisp air, the camaraderie and the extraordinary scenery made it one of those experiences that has stayed with me over the years. You certainly don’t have to tackle the Grand Canyon to get the same basic benefit. A local trail, state park or even a long walk through the woods can provide exercise, fresh air and a chance to disconnect for a while.
The Takeaway: Fall gives us a terrific window to get outside—so lace up the shoes, grab some water and enjoy it while the colors and cooler weather last.
