PLEASE NOTE THIS TRACK IS CURRENTLY CLOSED REFER TO THE DOC WEBSITE. - This track is rated by many as one of the most enjoyable hardcore rides in the country. Allow 4-6 hours (20km return - Grade 5) to bike up and then down. Or catch a helicopter up and just do the downhill (lasts for about an hour for those experienced riders! Allow longer if your not so speedy!). Kirwans Hill has a DOC hut on it so overnighting is an option too.
