Weather in Denali is extremely variable. Often changes in weather occur without warning. Many of our rangers tell visitors to expect sun, wind, rain, and clouds, and expect them all on the same day.

Average summer temperatures range from 33 to 75 degrees Fahrenheit. While we hope it doesn't, it has been known to snow in July, so be prepared. Wearing layers of clothing makes it easy to regulate your body temperature. Also, you'll find that a good waterproof raincoat is invaluable. Winters can be extremely cold with temperatures ranging from -40 degrees Fahrenheit and below to high 20s on warm days. Specialized cold weather gear is necessary for mountaineering and winter visits.

The park is open year-round to visitors. It is famous for spectacular landscapes, rugged peaks, and abundant wildlife. The Alaska Range, where Mount McKinley is located, effectively splits the park into north and south sides.

The North Side

The majority of visitors access the north side of the park by way of a single, 90 mile long road. Beyond Mile 15 of the Park Road, visitors cannot drive personal vehicles and must enter the park by bus, bike, or on foot. The main visitor center is located on the north side of the park. This is where the majority of interpretive programs take place. Wonder Lake, located at mile 85 on the Park Road, offers great views of Denali. The Murie Science & Learning Center is open year-round and serves as the winter visitor center. Rangers are available from 9:00 am to 4:00 pm in winter to answer visitor questions and help plan trips.

The South Side

Denali's south side is accessed primarily by mountaineers climbing Mount McKinley and other peaks in the Alaska Range, or by scenic flight tours. Climbers must check in with rangers at the Talkeetna Ranger Station before climbing Mount McKinley. The Talkeetna Ranger Station stays open year-round. Rangers at the station also offer interpretive programs throughout the summer.
