Wonderland Trail
This 93-mile trail loops around Mount Rainier, offering backpackers spectacular views of the mountain's many faces. Trekkers will be exposed to a range of landscape zones, from alpine meadows to lowland forests to pristine rivers and streams. Hiking the full length of the Wonderland Trail is often considered a greater challenge that summiting Mount Rainier. With a cumulative altitude change of over 20,000 feet, hikers are advised to break their days into 7-10 mile chunks, taking a total of 10-14 days. Registration and permits are required.
