Mountain Lakes Wilderness, located in the southern Oregon Cascades, was formed by a volcanic caldera and subsequent glaciation, resulting in a unique landscape with multiple alpine lakes. This Wilderness is notable for its perfectly square boundary, making it distinct within the National Wilderness Preservation System. Visitors can explore the 8.2-mile Mountain Lakes Loop Trail and other interior trails, offering opportunities for hiking and horseback riding amidst a landscape rich in geological history and natural beauty.
