Wind back down the road to 410 and head south, continuing south at Cayuse Pass on 123 toward Stevens Canyon and Ohanapecosh. Shortly before the road branches off to the Stevens Canyon Entrance and Paradise, you'll pass the Grove of the Patriarchs Trail. The Patriarchs are gigantic cedars, and it makes a very pleasant short walk, not at all demanding.
It's impossible to convey in a small photograph the impressive size of these trees.
