It's just over a mile along the road from Taplow station to the Woodland car park of the Cliveden Estate. Let me know if you would prefer to join the walk there, it is easy enough to finish the walk there too. National Trust membership required - entry will cost £19 if you are not already a member. There is a fair chance that other walkers can take you in as a friend.
We will then do a couple of the walks within the estate which have magnificent views, before having lunch at the cafe (or picnic nearby). Return via the Green Drive. Hopefully there will be some autumn colours to admire on the trees.
