Elmer City is a VERY small town of 240 residents, officially incorporated in 1947. Located on the Colville Indian Reservation, you’ll find an unexpected treasure with the lovely Downriver Trail. It's a 6 mile trail along the Columbia River that’s great for walking, running and biking. It begins along the river between the towns of Coulee Dam and Elmer City. You’ll enjoy the bird watching and wildlife viewing opportunities both along the trail and in the surrounding area.
