M5 from South West: Take J4A onto M42 East/North.

At M42 J3, go north on A435 signed Birmingham. Rural dual c'way for 2-3miles. 1st big roundabout - 2nd exit. 2nd big roundabout - 3rd exit (i.e. right turn) Maypole PH on corner.

Suburban for ~1.5miles. Mini roundabout - straight over. Continue past playing fields on left, Prince of Wales PH on right. Watch for traffic light pelican crossing and BP garage on left. Turn left at BP into Yardley Wood Road, then 1st right within 50m.

From the North: (I wouldn't start there - go to M42 J3)
