A small collection of stones in a circle, with one smoother flat stone in the center. Sarsens are a type of sandstone that formed on chalk deposits over 30 million years ago Glaciation cracked the layer and dragged the stones across the landscape As the ice melted, the stones were left scattered across the fields of Wiltshire.

A wonderful sweep of chalk downland located to the north of the Pewsey Vale and in the North Wessex Downs National Landscape. The reserve covers three hills and includes Alton Barnes White Horse cut into the chalk hillside. There are great opportunities for wildlife and landscape photography with views stretching across the Vale of Pewsey to Salisbury Plain. Pewsey Downs National Nature Reserve is also part of a Site of Special Scientific Interest (SSSI), recognising the range of chalk grassland plants and the associated butterflies (28 species). While you are there, also look out for the Sarsen stones, known locally as ‘Grey Weathers’.

Milk Hill 294m, Pewsey Down, Wiltshire (County High Top). A longish but easy walk over undulating hills to get Milk Hill, the county top for Wiltshire. Thought I would do Tan Hill as well to bag a trig point. Turns out there was no summit marker on Milk Hill or a Trig Point on Tan Hill. Still, a lovely walk and well worth doing. Took Walkers Hill as well which is a great historic tomb. Route Statistics: Easy undulating trails with minimal ascent really. 9.2km done in 2hrs with 250m of height gain.
