To
find Whitehall Farm, approach on the A30 from either the Honiton or the London
direction. From the Honiton direction make sure that you pass the
Little Chef and then in a quarter of a mile take the Luppitt turn off.
From the London direction pass through Monkton and the take the Luppitt turn
off on the right immediately on leaving the village.
When you have turned off the A30, in 100yds you will cross a narrow stone bridge over the river Otter. Immediately you are over the bridge, turn right. Proceed up the hill and after 7/10ths of a mile you will find the Farm in the left. Come up the long drive into the court-yard.
If you need help navigating from further away you can look at the "MutiMap" web site and change the Scale to fit your needs.
Entering a scale of 1 in 500,00 will be a good start.
