Please Note: this walk has already happened.

Ashdown House is set in the Lambourn Valley and this walk will let us enjoy the landscape and some of the interesting features of the geological history over the last 100 million years.

We will see a chalk valley, now with no water flow, sarsen stones and beautiful views.
