We thought we'd attempt a Memorial Day hike, braving crowds, but there was barely a soul on route 12, heading east from I-5. The signs at Cowlitz ranger station (in Randle) let us know that route 25 was closed at Benham Bridge, so we wouldn't be able to get to Norway Pass that way. (Access to Windy Ridge was thus also blocked.) We decided to try to get to Norway Pass via route 26.
It was tricky to actually find the turn to route 26 (not well marked), but we found it and it was a nice drive. Unfortunately, very close to the point at which the Norway Pass trail would've started (not far past the Green River trailhead), the road was washed out. Impassable for cars.
So we backtracked and did the Green River trail towards the Horse campground. Some snow and soft/wet spots, but on the whole very easy to traverse. Lush and green and beautiful. Got down to the campground (didn't see a soul there either) and then turned around.
