Use this trail to make Chi Ma Wan into a complete loop. Some tech rocky descents and nasty little climbs. Be especially cautious on the last 200 metres. Originally called Pierre's Trail, but name has changed to AA extension. Was once illegal, but now seems to be widely accepted by AFCD as acceptable to ride.
