Directions: Sumas Mountain is the mountain a short distance east of Abbotsford that highway 1 goes by. There has been considerable development on Sumas Mountain, hopefully the trails to the peak are still intact. There is an eastern and western trail to the peak. The western trail is described here. Heading east from Abbotsford on highway 1 take Exit 95 (Whatcom Road). Take North Parallel Road heading east to Sumas Mountain Road. Go north on Sumas Mountain Road for approximately 9KM (5.6 miles). Close to where the trail starts the road may turn to gravel. This was the case back in 2003. It may be paved now? It is easy to miss the entrance to the trail which will be on the right hand side (east). The trail entrance was part way through a left hand curve as the road headed downhill. There was enough room a bit past the trail entrance to pull off the road and park. The trail is well marked, crosses a creek, a gully and then climbs following old logging roads. Along the way more streams are crossed and the trail comes to a small scenic lake, Chadsey Lake. Go around the south side of the lake and pick up the trail on the east side of the lake. The trail now climbs to the double peaks. On a clear day from the peaks there are excellent views of Mount Baker and the Fraser Valley. The photos below from 1999 show parts of the trail and some of the viewpoints.
