With its mountain location and climate, the Flagstaff area is a hiker’s utopia – Spring through Fall. Flagstaff area hiking trails in the San Francisco Peaks (Arizona’s highest range) lead to wildflower filled meadows, immense fern gullies, glistening aspen groves, pine filled expanses, and impressive summits. Easy hikes wind across foothills. While ambitious trails conquer high peaks – including Mount Humphreys, Arizona’s tallest. Thunderstorms roll in quickly in Summer. So come weather prepared. In winter many trails close due to seasonal snow.
