Sumas Mountain Trail

The Sumas Mountain Trail is a popular out-and-back hiking route near Abbotsford in the Fraser Valley that climbs uphill through a scenic stretch of forest to the calm waters of Chadsey Lake before continuing on to the summit of Sumas Mountain. We recommend bringing a 4×4 or high-clearance vehicle as the road to the trailhead isn’t in great shape. This trail is connected to a dense network of hiking routes just to the south, so hikers should bring along a trail map or GPS in order to stay on the correct path. This route can also become fairly wet and muddy, so proper hiking footwear is recommended to stay both dry and comfortable over the long incline of this trail. Additionally, the forested nature of the trail and its proximity to water makes this route prone to bugs. Bring bug spray during warmer seasons.

Setting out from the trailhead off Sumas Mountain Road, follow the trail into the dense forest cover as it crosses over a creek and begins to climb uphill. As you meander through the forest, you will notice a steady gain in elevation the entire way up to Chadsey Lake. Reaching the fork in the trail at the lake’s edge, follow the path to the right to skirt around the southern side of the lake. Here, you will gain another 656ft in elevation as you make the final push to the summit. When you reach the viewpoint atop Sumas Mountain, you will have great views over the Fraser River, Chilliwack to the east, and Mission and Abbotsford to the west. When you’ve taken in the sights, head back down the trail and make your way around the north side of the lake for a bit of variation, returning to your vehicle to wrap up your hike along the Sumas Mountain Trail.
