With average temperatures ranging from 5 to 15°C, March offers a refreshing climate that's great for outdoor adventures like hiking, skiing, and exploring the scenic beauty of the region.
Idaho experiences its peak tourist season from August to October, when visitors flock to enjoy the vibrant autumn foliage and a variety of outdoor activities. This is an ideal time for those who appreciate the great outdoors, as the crisp air and colourful landscapes make for fantastic hiking, biking, and even fishing in the many rivers and lakes. The mild weather enhances the experience, allowing you to comfortably explore the state's national parks, such as the breathtaking Sawtooth National Recreation Area.
If you're looking for a more budget-friendly option, consider visiting in January.
