"One of the country's oldest national parks, Mount Rainier is an active volcano and the most glaciated peak in the lower 48 states. Visitors enjoy the park year round, with snow sports in winter and hiking, fishing, boating, camping, and bicycling during July and August. More than 260 miles of maintained hiking trails through forests, river valleys, meadows and along streams offer views of wildflowers in summer and glaciers year round." - Travel + Leisure Editors
