Leave the M4 at the Magor services which is junction 23 and then follow the signs for Caldicot. Follow the main road (B4245) through Magor - Undy and Rogeit. There is only one road so stay on that, when you come into Caldicot you'll come to a set off traffic lights, go over them and go straight over the next set and carry on that road. You should pass the Junior school on your left (Durand School), take the second turn on your left into Chepstow Road. Follow the road to the mini roundabout, go straight over into Sandy Lane and then take the third turning on the right into Neddern Way and follow the road around and the church is in the right hand corner with a large car park.
