Travelling from the North via Cardigan or the East via Camarthen.
On reaching the roundabout at Kilgetty, take the A477 heading towards Pembroke Dock (please ignore the signs for Tenby and Saundersfoot at this point). At the next roundabout (after approx. 5 miles) turn left on to the B4318 signposted for Tenby.
After travelling approx. 2 miles from the roundabout, look out for the brown directional sign on your left for Trefalun. Turn left into Devonshire Drive (opposite the main entrance for Anna's Welsh Zoo), following the sign for Saundersfoot. Trefalun is the 2nd entrance on your left.
