With Devon bring on the toe-end of England, routes to Exeter are pretty limited in number. Essentially, head down the M4 towards Bristol, then take the M5 southbound which terminates at Exeter. However, there are 3 Exeter junctions on the M5 (29, 30 and 31), so it's imprative that you take the right one - junction 31.
Take the A30 off the motorway, turning off after 2 miles onto the A377. Head up the A377 to the roundabout after 1.5 miles and take the 4th exit onto Frog Street (B3212) which becomes Western Way. Following the B3212 route leads you up to St James after just more than 1 mile and a roundabout.
Take the second exit here onto Old Tiverton Road and the next left into St James Road. The ground is dead ahead.

The ground is only 0.5 miles from Exeter Central but many of the trains will not stop here but at St. Davids only, and you will need to change to get to Central. This is no real hassle though, as the trip between the two is only 3 minutes long, and run every 15-20 minutes.
If changing at St Davids then you can get a direct train to St James' Park (Exmouth line), as there are tie-ins with the train companies so there are trains on match days stopping there at times suitable for the match.
Exit from the rear of Exeter Central and turn right in New North road, before taking the left hand turn into Longbrook Street. Pass the Black Horse pub on the left, and at the grass triangle verge right and then right again into York Road, turning left at the school into Well Street.
When arriving at the ground, go right to get to the away terrace (St James' Road), or continue straight for the seating area.
