A great 5.5 mile walk that could be extended or shortened to suit.
Starting from the public car park in corfe, the route follows the road to Corfe Common. Crossing the common, there are a number of path choices but following a straight line brings you down to West Lynch and the long uphill walk to Kingston. Once in the pretty village of Kingston, you'll find the Scott Arms, a pleasant pub and worthy of a pitstop (often very busy in mid-summer though).
There are number of routes that can be taken from here, either heading South to Chapmans Poole, or South East to Worth Matravers, for example. We were pushed for time and so headed East, just past a converted church and down a long, gentle descent through fields to Afflington Wood, joining the Purbeck Way and returning towards Corfe.
We, once again, crossed Corfe Common and decided to explore part of the village that we've not seen before and so headed through Towns End and across some commonland before reching the road and turning to take us back to the car park.
A very nice shortish walk for a spring afternoon.
