Barbury Castle and Hackpen Hill Circular
Wiltshire
Barbury Castle is an Iron Age hillfort perched on the Marlborough Downs above Swindon, and this 7.7 km circular follows the Ridgeway and surrounding chalk tracks across open downland with long views in every direction. The fort's ramparts are still impressive and give the starting point genuine presence before the route drops onto broad, white chalk tracks that run between arable fields and open grassland. The 235 m of climbing comes in steady waves rather than sharp pulls, and the terrain is exposed throughout with little shelter from wind or sun. On clear days the views stretch across the Vale of the White Horse and into the Cotswolds.
This is a dog friendly walk that suits energetic dogs who thrive on open ground and moving air. The broad chalk tracks give dogs space to range, and the constant wind carries scent from all directions, keeping noses active throughout. Off-lead walking is limited as livestock graze the surrounding downland and arable margins, so leads should be carried and used where sheep are visible. The chalk surface is firm and drains well, making this a reliable option in wet weather when lower ground turns to mud. The exposed nature of the route means it can be harsh in wind and rain, so it suits fair-weather outings best. Toilets are available at the country park car park.
