At the end of the M5 at Exeter, take the A380 towards Torquay.
At the sign for Teignmouth turn left onto the B3192. At the bottom of the hill turn right. You will see the estuary bridge to Shaldon. Turn right going across the estuary bridge.
As you come into Shaldon, (do not go up the hill) but take the right hand fork immediately after the mini roundabout onto B3195 which keeps the river on your right hand side.
Devon Valley Holiday Park is 1 1/2 miles along here on the right.
