Barton Hills

Barton Hills National Nature Reserve (NNR) is a fine example of downland and woodland in the north Chilterns. It is a popular destination for walkers, families and wildlife enthusiasts. The whole site is open access, and there are a number of footpaths throughout.

Main habitats: lowland chalk grassland, beech woodland

Features of interest

Colourful wild flowers cover the chalk grassland, including rarities such as the Pasque flower, greater pignut and field fleawort, plus classic downland plants like marjoram, rock rose and scabious. In summer you will see plenty of butterflies including chalkhill blue, marbled white and dark green fritillary.

The woodland contains an important population of large leaved lime trees and is also home to the scarce plant herb paris. Also, look out for mammals including stoats, weasels and hares.


The nearest train stations are in Luton and Hitchin.

Take local bus number 81 which runs from Luton to Barton-le-Clay.

Barton Hills is immediately south of the B655 between the town of Barton-le-Clay (0.5 kilometres west of the reserve) and the village of Hexton (1 kilometres to the east).

Access to the site is via footpaths from the B655. In Barton-le-Clay paths leading to the reserve are at the end of 2 roads: Old Road and Church Road, both off the B655.

The terrain at Barton Hills is steep and difficult in places and is mostly unsuitable for wheelchairs. Depending on the weather, the path alongside the stream from the hay meadow towards the spring can be suitable for wheelchair access.


Volunteer on the second Thursday of every month from 10am to 4pm to carry out tasks such as scrub management and fence and gate installation. For dates and further details see the North Chilterns Volunteering website.

King’s Wood and Rushmere

The reserve is an important area of ancient semi-natural woodland. In early mediaeval times it was part of the royal manorial estate of Leighton, hence the name ‘King’s Wood’. Part of Rushmere Country Park is included in the reserve.

Main habitats: woodland

Area: 148 hectares

Management: jointly owned and managed by Central Bedfordshire Council, the Greensand Trust, the Wildlife Trust for Bedfordshire, Cambridgeshire and Northamptonshire, and Tarmac.

Features of interest

The site lies on an unusual mixture of soils. Birch, sessile oak, bracken and heather grow in the sandy areas, with pedunculate oak, hornbeam and dog’s mercury on the clay. There are small-leaved lime trees here and a large population of lily-of-the-valley. The site is also home to rare mosses and fungi and there are recent records of the purple emperor butterfly here.

Additional information about the reserve is available from the Greensand Trust.
