Beautiful spot to sit on a log and contemplate life and the view

Moderate trail to explore and enjoy the beautiful hidden sceneries

There is a phenomenal view to the north from here - long sweeping views of the forested hills and down towards Great Kimble and beyond. This is the stuff of poets live for! By the way, do give the Granglelands and the Rifle Range information board a read for more information about this beautiful chalk grassland area. The place is teeming with life: including butterflies such as Brimstones, Common Blues and Marbled Whites to be spotted in the spring and summer months. A great place to slow down for a bit on your jog!

This quarry is a Site of Special Scientific Interest and well known by geologists for its phenomenal history. Packed with fossils, some of the finds here date back 100 million years. There's no public access, but you can catch glimpses of its bright high-alkaline water from the surrounding footpaths.

Moderate trail with good fitness level required but once at the top the views are amazing

Chinnor, Chalk and Cement Mr. W. Benton's Cement and Lime Works opened in Chinnor in 1908, but cement making on a truly industrial scale did not begin until 1919. Output of cement from Chinnor peaked at about 5600 tonnes per week in the 1990s. Up to 120 people were employed at any one time. The cement works closed in 1999 and there are plans for the re-development of the site, using the flat areas for housing but also with opportunities for recreation and conservation in the water filled quarries The scale of chalk extraction for cement making can be seen from a short walk along the Ridgeway National Trail. The Ridgeway runs on a high causeway between the large quarries, giving views of the pits through the boundary fences. (Do not cross over or through the fences). Geology One of the chalk quarries has been protected as a geological Site of Special Scientific Interest as it has particularly good exposures of both the Lower Chalk and Middle Chalk geological layers. Both layers have given upimportant fossil ammonites.

The wetland meadows of Cock Marsh are very important for rare plant species, breeding waders and overwintering birds. Part of the site is designated as a Site of Special Scientific Interest (SSSI). The steep chalk grassland swiftly changing into marshy, acid meadows has created an ecosystem of rare and interesting species. As part of the historic channel of the Thames, the ponds here support specialist plants like water violet, marsh arrowgrass, marsh stitchwort, marsh pennywort and water hemlock. The rare sedge Cyperus fuscus (brown galingale) is found here and in only a handful of other sites in Great Britain. It relies on cattle to tread or poach the ground on the pond edges to create the perfect habitat to grow. The cattle here work hard to help to maintain a rich botanical diversity of grassland habitat. https://www.nationaltrust.org.uk/maidenhead-and-cookham-commons/trails/cookham-and-cock-marsh-walk
