Higher Penmayne Farm has two entrances but by far the easiest way to the site is to turn off the B3314 into Keiro Lane (signposted Rock, Trebetherick and Pityme).  Follow this road for 1.8 miles past the sign for St Minver Lowlands and towards Rock, until you see a wide-splayed junction on the left signposted Penmayne.  (The junction is opposite the Spar store and fish & chip shop.)   Follow the Penmayne turning for approximately 150 metres and  you will see the entrance to the farm ahead of you (at this point the road bends sharply to the right).  There are two drives ahead of you, to reach the farmhouse/campsite please follow the drive on the right-hand side, past the access control barrier and up to the house.
