Just past a clearing the road through the golf course forks - stay right. If you end up going left you will eventually pass a sign for a wastewater treatment plant ... you've gone too far if so.
Thanks Rob, I amended the text to reflect that in the "Approach" section. Hopefully it saves someone some walking :)
Thanks for recommending this route to us Peter - it was great fun ! Will have to come back for the last pitch someday ... with goretex this time :)
