By car Take the A30 to the Chiverton Cross roundabout and take the exit onto the B3277 (Penwinnick Road) signposted St Agnes.
At the next roundabout take the B3277 exit to St Agnes.
Follow the B3277 for about 5km until you reach a mini-roundabout on the edge of the village. Turn right into Vicarage Road. You are in the Churchtown area of St Agnes.
Follow Vicarage Road (which is really the 'High Street') until you see the Parish Church on your right and the St Agnes Hotel on your left. Take the road up to the left (Trevaunance Road).
Keep on Trevaunance Road ignoring Wheal Friendly Lane (it's a cul-de-sac) until you come to Rocky Lane on your right.
About 700m down Rocky Lane you will see the entrance to Wheal Friendly Gardens on your right just after the entrance to Little Orchard Village on your left.
The drive is unmade (but quite firm) and there is a gate with a combination lock to gain entrance.
There is only one parking space in front of Treth house next to the decking, however there are local car parks available, one is just below towards the beach.
