Sun Lakes-Dry Falls State Park Fast Facts

Park Overview

Sun Lakes-Dry Falls State Park showcases one of the most dramatic examples of Ice Age flood geology in North America, where the massive Missoula Floods carved the spectacular Dry Falls cliff and surrounding coulee landscape that serves as a prime example of shrub-steppe habitat.

The park’s distinctive character emerges from its remarkable transformation of harsh desert terrain into a recreational oasis, featuring nine freshwater lakes created by the same catastrophic floods that formed the towering basalt cliffs, while comprehensive facilities developed through decades of Civilian Conservation Corps work and subsequent improvements create modern amenities within this ancient landscape. Located at the head of the Lower Grand Coulee along State Route 17, the park preserves both geological significance and diverse recreational opportunities that attract visitors seeking unique high desert experiences.

Established through systematic land acquisition from 1933 through 1972 and enhanced by the integrated Sun Lakes Resort operating within park boundaries, Sun Lakes-Dry Falls State Park serves visitors seeking both educational experiences about Ice Age geology and comprehensive recreational facilities. The adjacent Dry Falls Visitor Center provides interpretive exhibits explaining the dramatic flood events that shaped this landscape, while extensive hiking trails offer panoramic views from tabletop cliffs overlooking the desert oasis below.
