Twin Sisters are two pillars of basalt that jut from the cliffs along Wallula Gap overlooking the Columbia River. Geologists say the rock formation is the result of erosion from a great flood near the end of the last Ice Age, about 12,000 to 15,000 years ago. A Cayuse legend states that the natural monument was formed when Coyote, an animal spirit, fell in love with three sisters, then became jealous of them and turned two into stone. The third was turned into a cave, says the legend. Regardless of the reason the pillars were formed, the trail here—though short—provides some remarkable adventures. From the area at the base of the Twin Sisters Rock to the highland area rocks to the south, you’ll enjoy amazing views of the Wallula Gap on the Columbia River.
