Barton Hills are situated southeast of the village of Barton-le-Clay in the English county of Bedfordshire.

[2] The steep well-grazed slopes are a classic downland habitat, however there were no sheep on the hills from about 1930 until the 1980s and woodland has formed on the hillside to the west of the stream which issues from Barton Springs.

The reserve is the main site in Bedfordshire for the pasqueflower (Pulsatilla vulgaris), and in some years over a thousand flowers are present.

In the 21st century, the Hills were used as a training ground by undercover operative Morten Storm and Islamic terrorists from nearby Luton.

[4] To the east of the main reserve area, near the border between Bedfordshire and Hertfordshire, (51°57′28″N 0°24′11″W / 51.9577°N 0.4031°W / 51.9577; -0.4031 (Barton Gravel Pit)) there is Barton Gravel Pit, a nature reserve managed by the Wildlife Trust for Bedfordshire, Cambridgeshire and Northamptonshire.
