One aspect of Cornwall is that there is only one southern road in, the A38 from Exeter, which the M5 becomes going westward from there! From Exeter to Plymouth is a little over 40 miles. To reach St John, there are two alternatives, one using the Tamar Bridge, the other going via the Torpoint chain ferry. The first is longer by about 20 miles, yet ironically it is quicker in busy times in summer! The queues at the ferry can lead to a 40-minute wait.

Via the Ferry - turn off the A38 to Plymouth at the Marsh Mills roundabout. Follow signs for the city centre and then the Torpoint Ferry. Be careful, there is also a continental ferry port: you do not want that one. Once over the ferry (no charge going into Cornwall unless you are on a motorbike, costs £1 to get out again!), follow the road out of Torpoint. Pass the RN oil depot on the right and then the entrance to Antony House. After about another half a mile, turn left. It is easy to spot as there is a filter lane for traffic turning right from the other direction. At the crossroads, 50 metres, go straight on. It is signposted St John. Follow this road, but beware, it does become narrow and winding. Do not branch left to the ford after the bridge (especially if the tide is in!). The road leads to the centre of St John, Lytherva is on the left opposite the pub.

Via the A38 - continue on the A38 into Cornwall via the Tamar Bridge (same rule for charging applies – the bridge is run by the ferry company!). Once over it and through the tunnel, you will come to a roundabout at the top of the hill. Go straight over (second exit) and carry on for another 10 miles. After a railway bridge over the road is Trerulefoot roundabout. Turn left here (first exit). Follow this road for about 8 miles until you come to Antony. On your right is the Ring o’ Bells pub. Turn right just after it and almost immediately left. Again, this is a narrow lane – take care. Follow this to the T-junction in St John. Turn half right (not the sharp right) and go to the centre of the village. Lytherva is on the left opposite the pub.
