From Blandford, follow signs for A350 Poole. Charlton Marshall begins just after a Peugeot Dealership and there is a 30 mph speed limit. You will pass the church on the left hand side. We are approximately 100 yards past the church on the right. There is a high brick wall, towards the end of which is a small lay-by. Drive over the lay-by and Keston House is on the left.

From the south, after entering Charlton Marshall on the A350 you will pass The Charlton Inn on the right hand side. On the left are a small green and a road joining. Almost immediately you will see the lay-by and the terracotta topped brick pillars forming the entrance.
