Mount Rainier National Park is located in west-central Washington and is ideal for hiking, mountain climbing and scenic drives. Most roads are open from late May to early October, which allow for both stunning views and access to a wide range of hiking trails and other sites. Hikers will find forests with cedar, hemlock, and fir trees as well as streams and wildflower meadows. On Rainier's alpine slopes, visitors will find firs, glaciers, and tundra. Mount Rainier, an active volcano, is the most prominent peak in the Cascades, and it is covered by 26 named glaciers including Carbon Glacier and Emmons Glacier, the largest in the continental United States. The mountain is popular for climbing, and more than half of the park is covered by subalpine and alpine forests. Paradise on the south slope is one of the snowiest places in the world, and the Longmire visitor center is the start of the Wonderland Trail, which encircles the mountain.
