We did this in January, but it was low enough elevation that there was no snow. And though the trees were bare, the forest was still green with moss and ferns.

Just past the Bridge of the Gods, on the Washington side, is a network of jeep roads that web through the mountains. This one starts near Skamania and goes just below Table Mountain, in a combination of paved, dirt and jeep roads, and includes a long climb in loose rocks that will beat you up and wear you out quick.
