Grange Chine and Marsh Chine
These two chines form the largest chine feature on the Isle of Wight. Grange Chine starts at the southern edge of Brighstone and runs south-west, crosses under the A3055 Military Road at the hamlet of Marsh Green then continues for about 500m to reach the beach at Brighstone Bay. Marsh Chine starts to the east of Marsh Green alongside the A3055 and runs west where it joins the larger Grange Chine before it reaches the beach.
Both chines have much shallower sides than other chines on the Isle of Wight and are extensively covered with hardy bushes, stunted trees and scrub.
The Chines drain water from the southern slopes of Brighstone Down and from as far as Shorwell to the east. The stream ( the Buddle Brook) formed is significant enough to power two mills, Yafford Mill and Brighstone Mill, and where it finally drains into the sea the stream is at least 4m wide. Once the stream reaches the pebble beach it soaks in and disappears.
The Isle of Wight Coastal Path crosses Grange Chine via a wooden footbridge near the beach.
