Ashton Road is in Marsh Barton near Exeter Retail Park (Comet, Argos, Staples, Currys etc), just off the A377 Alphington Road.

MacDonalds is opposite and the Vauxhall garage is on the corner.

Follow the road as far as you can, the Scout HQ is the very last building.  There is ample parking.

Bus routes A and B pass nearby.
