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.
