Day Hike - Cowiche Canyon


Day Hike - Cowiche Canyon

On the sunnier east side of the Cascades, Cowiche Canyon is always stunning, but especially in fall colors. We'll be enjoying those colors, learning about the Geology and bird watching. This hike will also include a second short hike along the Garry Oak trail near Snow Mountain Ranch.
