About Onalaska
Tucked into the rolling hills of Lewis County along Highway 508, Onalaska offers quiet rural living with easy access to the Interstate 5 corridor. Located about ten miles southeast of Chehalis, it allows residents to enjoy a peaceful, open setting within a short drive of regional shopping and services. The town grew around a bustling early-twentieth-century lumber mill, and its iconic 225-foot brick smokestack still stands beside Carlisle Lake as a nod to that heritage.
Today, much of the community gathers around Carlisle Lake, where paved walking trails, fishing spots, and calm water make it a favorite outdoor retreat. Local school pride runs deep, with students even helping raise and release thousands of young coho and steelhead into area streams each year. Every autumn, neighbors turn out for the Onalaska Apple Harvest Festival, bringing parades, pie contests, and farm tours to this friendly, scenic corner of southwest Washington.
