      The FSR closures implemented after the storms have been rescinded. However, some of the side roads at Sumas did see damage in the storm. Use with caution.

      Sumas Mountain is one of the most familiar mountains in the Fraser Valley. With recent trail additions like Squid Line, it's become a local destination.
