My wife and I hiked to Mount Si with our hiking group. We went up Old Mt. Si Trail and came down the new trail and traversed via Douglas Fir Trail. By taking the new trail down we made it easy for our knees. The weather was mostly sunny. The temperature was 51 F when we started at the trailhead and 43 F at our lunch spot and 66 F when we got back to the trailhead. There was some snow near the summit. The view at our lunch spot on the rocks was pretty good, but Mount Rainier was hidden in clouds.
