From the South: (recommended for caravans)

Leave the M5 at junction 27 and take the A361 signposted Tiverton. After 7 miles of dual carriageway, turn right at the roundabout signposted Bampton. Turn left at the Exeter Inn roundabout and take care to follow the A396 two miles later at the Black Cat filling station (ie. turn right then immediately straight over). 
Do not go through Dulverton but continue on the A396 past Exebridge for a further 7 miles. Upon entering Bridgetown, turn left immediately past the Badgers Holt Inn and the site entrance is on your right.

From the North:

Take the A396 from Wheddon Cross travelling south signposted Tiverton. Upon entering Bridgetown, the Mill House is the first building on your right.  Turn right immediately after the Mill House and the site entrance is on your right.
