Flagstaff is the largest city in northern Arizona, nestled amidst one of the largest pine forests on the planet, Coconino National Forest. Known as the City of Seven Wonders, Flagstaff provides access to a frequented and easily identifiable natural site: the Grand Canyon. Numerous other parks and historic areas surround the city, including the Wupatki National Monument, Fort Tuthill Military Museum and Meteor Crater park. Flagstaff sits at an altitude of 7,000 ft (2,100 m), giving it the distinction of being one of the highest cities in the United States. Home to both Northern Arizona University and the Center for High Altitude Sports Training, athletes come here to take advantage of Flagstaff's elevation while training. Despite Arizona's reputation as a desert state, this city enjoys four distinct seasons, including snow in the winter. Combining the ability to have snow with its mountainous terrain, Flagstaff boasts Arizona Ski Bowl, which offers both downhill and cross-country skiing trails.
