Hurst Castle Spit
Walk along this long shingle spit to one of Henry VIII's Device Forts on this lovely coastal walk in Hampshire. The walk starts at Keyhaven in between Lymington and Milford-on-Sea. You follow the shingle spit for about 1.5 miles out to the castle where there are splendid views of the nearby Isle of Wight and the south coast.
If you would like to continue your walk you could follow the sea wall through Keyhaven Marshes towards Lymington.
