Black oak, American sycamore, and sweetgum are a few of many common trees in the Cossatot River Corridor. Tree leaves, bark, and buds are all useful hints to tell us what kind of tree we are observing. Join a park interpreter on a hike as you learn how to identify different tree species, no matter the time of year. We will be hiking on the River Corridor Trail for 2 miles starting at the Low Water Bridge. Trail rated easy to moderate.
