"Unlike many national parks out West, Big Bend National Park’s peak season occurs from October through April, as the Texas heat dies out. This cooler weather is ideal for the park’s most popular activities, hiking and stargazing, so be sure to bring appropriate footwear, a water bottle, and a few layers (temperatures drop even further at night). If you time your visit right, you may be able to see some of the fall colors on the slopes of the Chisos Mountains." - Travel + Leisure Editors
