Dundry Hill is immediately south of Bristol, England: it includes farmland, a small number of houses and a church.

At the hill's eastern end the southern slopes are within Bath and North East Somerset, and the northern slopes are within the city and county of Bristol, including the highest point in that county.

At the eastern end is Maes Knoll, near Norton Malreward, an Iron Age hillfort and the start of Wansdyke.

The Main Road Quarry exposes a fine section in the Middle and Upper Inferior Oolite,[3] with the rocks lying stratigraphically below them visible at Barns Batch Spinney.

This contrast is direct evidence for movements of the Mendip Axis in Middle Jurassic times, making this an outstanding site for its bearing on studies of palaeogeography.
