Leaving Penzance behind you, with Sainsburys supermarket on your left, take the second exit at the roundabout on to the Long Rock bypass. This is a mile long stretch of dual carriageway. At the next roundabout (Newtown Roundabout), stay in the left hand lane and turn left (signed A30 Redruth). After a mile, you will come into the village of Crowlas. As you enter the village speed limit, you will reach a crossroad. Turn right (signed Rospeath)and follow the winding country lane without turning off for approximately 1.5 miles. You will come to a bridge over the road (carrying the Marazion bypass). Go under the bridge and follow the road around a sharp left bend. As you start climbing the hill towards Marazion, you will see the entrance to Wheal Rodney Holiday Park just on the right-hand side.
