Looking for a longer forest hike yet something still good for families? The Green trail is great for older kids that can walk a little further and enjoy the adventure of a few ups and downs. Parts of the trail have steep inclines. 

Start along the boardwalk at the Twin Valley Welcome Center for views into the ravine. You may hear some birds that like to hang out near Twin Creek, like the kingfisher. 

You can hike this loop in either direction. If you hike it counterclockwise, you'll quickly drop to the river on some rooted doubletrack and be greeted with a smooth flat stretch along the creek for the first half of the loop. The second half of the loop is undulating back up to the visitor center along shaded trails with rocks and roots.
