Monarch Whistle has been re-routed since its original layout and is much better now. Named after the 8:00, 12:00, and 5:00 steam whistles from the old Monarch Rubber Plant in Spencer that people have grown to love, this trail is really flowy. First time riders to Ben's Run system should come to the top and park at the winery. Ride out past the artist colony and past the cell tower to the gate. Start your ride here and follow the Monarch Whistle signs. Light it up, it's time to go fast.
