Keyhaven to Hurst Castle

Keyhaven to Hurst Castle is a 4.5-mile out-and-back from Keyhaven Amenity Car Park, along the harbour sea wall and out over Hurst Spit. There is almost no climbing, but loose shingle makes the final stretch slow and tiring. Allow about two and a half hours for the return walk, before visiting the castle. Go for the big Solent views and the unusual approach, not a quick stroll.

From central Keyhaven, follow the harbour wall past the moorings, then cross the Sturt Pond channel and turn onto the spit. Views open over salt marsh, the Isle of Wight and the Solent. The spit is loose shingle rather than a firm path; a faint, firmer trodden line can help, but it is not always easy to follow. The exposed stretch can feel tougher in wind than its low elevation suggests.

Hurst Castle was built for Henry VIII between 1541 and 1544 to guard the Needles passage into the Solent, then expanded with Victorian gun batteries. Old gun emplacements and Hurst Point Lighthouse mark the end of the spit. From the ridge, the castle and sea make a strong view back along the route; keep the raised shingle in the foreground to show the shape of the spit. The seasonal Castle Café sits outside the walls for drinks, snacks and cakes. The Gun Inn is a separate pub stop beside the car park at Keyhaven.

A ferry links Keyhaven with the castle and can replace one leg when it runs, cutting the walking roughly in half. Departures depend on season, weather and tides, so check before setting out. Keyhaven Amenity Car Park has pay-and-display parking and public toilets. Dogs are welcome on the route and ferry on a short lead; Hurst Spit is a nature reserve with nesting birds. The approach road by Sturt Pond can flood at high tide, so do not attempt it when flooded.
