Standing 14,410 feet above sea level, Mount Rainier is an icon in the Pacific Northwest that attracts close to 10,000 climbers each year. Striving for the summit—and, if the odds are in your favor, reaching it—is an immensely rewarding challenge.
The active volcano is the highest peak in Washington State and the most glaciated peak in the lower 48 states. To get to the top, you'll need to gain more than 9,000 feet of elevation, hike at least eight miles and travel on crevassed glaciers. A typical summit attempt requires 2–5 days, but it's well worth the effort.
There are dozens of climbing routes up Mount Rainier, offering a wide range in difficulty and popularity for mountaineers. About half of the climbers attempting to summit reach the top.
If you're planning to climb Mount Rainier, you must be in excellent physical shape, properly trained and equipped with the correct gear. Weather, route conditions and the effects of altitude will also contribute to the outcome of your summit attempt.
Mount Rainier Weather
Weather changes rapidly on Mount Rainier and rain, snow and frigid temperatures can occur any time of year. Know the forecast and be prepared for changing weather and sudden storms with extra clothing, rain gear and shelter.

Mount Rainier Permits
When you arrive at Mount Rainier National Park, you will need to pay an entrance fee or show a valid annual pass. To climb the mountain, you will also need the following:
Climbing Pass: Anyone climbing on glaciers, or above 10,000 ft., must purchase a Mount Rainier Climbing Pass, which is valid for the calendar year. You can buy your pass in advance or on the day of your climb.
In the summer, you can get a climbing pass in person at the Climbing Information Center in Paradise; the Jackson Visitor Center in Paradise; the White River Wilderness Information Center at the White River Entrance; the Longmire Wilderness Information Center; and the Carbon River Ranger Station. Be sure to check the operating hours of the location you plan to visit. You must have a valid photo ID to purchase a Climbing Pass.
Wilderness Permit: Climbers who plan to camp overnight are also required to get a Wilderness Permit. Mount Rainier limits the number of campers in each wilderness zone, so it’s best to make advanced reservations for your permit. You’ll have to pay a small fee, but you’ll be able to secure your campsite ahead of time. The park starts taking reservations on March 15.
About 30 percent of permits are held to be issued in person on a first-come, first-served basis for free. These permits can be issued on the day your trip starts, or up to one day before your trip starts. If your dates are flexible and/or you are climbing midweek, permits are generally easy to come by even in peak season.
Registration: Your party must register in person for the climb on the day the climb begins (or the day prior).
Permissions: Anyone younger than 18 years old must have written permission of a parent or legal guardian before climbing.
Solo travel above high camps or anywhere on glaciers is not allowed except with written permission from the Mount Rainier National Park Superintendent.
