Nestled in the rolling chalk hills of the South Downs, the Halnaker Windmill Trail offers a perfect afternoon escape. Starting from the car-park at Boxgrove village hall, you’ll cross quiet lanes and head into Mill Lane, a leafy “tunnel of trees” formed by an ancient hollow-way. This enchanting path is actually the route of Stane Street, the Roman road from London to Chichester.
The walk gently rises as you leave the tree-tunnel and climb up to the windmill sitting atop Halnaker Hill (approx. 128 m elevation). The final stretch rewards you with sweeping views across farmland, down to the coast — on clear days you might even glimpse the Isle of Wight.
Why it matters
The windmill itself is a striking landmark: a tower mill built in the mid-18th century (c. 1740s) for the Duke of Richmond by the Goodwood estate. It was operational until it was struck by lightning in 1905, after which it gradually fell into disuse. Today it stands as a Grade II listed building. The hillside beneath is also rich in nature: chalk grassland here supports wildflowers and butterflies, making the trail a nature-lover’s bonus.
Practical tips
Wear comfortable shoes for the hill climb. Start from Boxgrove village hall for parking and signage. Allow about 1.5-2 hours for the full route, though you can shorten it by heading back before the summit. If you plan a clear afternoon, bring a camera — the viewpoint at the windmill is special.
Whether you’re keen on history, countryside scenery, or a gentle hike, the Halnaker Windmill Trail delivers a memorable outing.
