From Exeter:

Keep following the A380 dual carriageway (signed to Torquay) until you reach the Newton Abbot turn-off at the Penn Inn junction. Follow the Brown Tourist Signs and move into the left lane which filters traffic going to Newton Abbot from Torquay traffic.

From Newton Abbot:

Follow Torquay signs to Penn Inn junction.

From Penn Inn junction:

Follow signs to Milber and Combeinteignhead up the hill for about 50 metres and then turn sharp right again at traffic lights. You will soon be on a wide country road passing through mature woodland. Plant World is approximately one-and-a-half miles out in the rolling countryside. We are at the VERY TOP of the long hill on the left-hand side past the fitness centre.
