Bokerley Dyke is a substantial linear earthwork, approximately 5.75 kilometers (3.6 miles) long, located on Cranborne Chase. It runs along part of the border between Dorset and Hampshire, specifically between Woodyates and Martin. It is part of a larger Scheduled Monument that also includes Grim's Ditch and other earthworks. The dyke has a multi-period history. It is believed to have originated in the Bronze Age or Early Iron Age as an important political and cultural boundary. In the 1st century, it was cut through by a Roman road, Ackling Dyke, which ran between Old Sarum and Badbury Rings. In the 4th century, the dyke was remodeled and brought back into use. During this period, the Roman road was blocked. A coin of Valens found during excavations dates this activity to shortly after 364 AD, with some sources suggesting it was built between 367-368 AD. This remodeling may have been a defensive measure against attacks on Britain by Picts, Scots, and Saxons. The Roman road was eventually reopened, but the dyke may have continued to be used as a boundary after the Roman administration ended. Today, it still forms part of the border between the counties of Dorset and Hampshire.

Whitsbury Castle is an early Iron Age hill fort. The banks were reinforced in medieval times, but today are mostly tree covered. It's a nice place to run with a footpath going around the base.

‘Harnham Chalk Pit’ as it is marked on maps, is a long-abandoned chalk quarry that has been taken back by nature. Several different levels accessed with paths that scramble up the quarry sides. I imagine they will be lethal after recent rainfall! Loads of butterflies and wildflowers seen today (August). Unfortunately litter appears to be an issue here, not excessive but noticeable. It baffles me why anyone leaves rubbish indiscriminately in locations like this. Great distant view of Salisbury Cathedral from upper levels.
