Walk Notes The central attraction of this North Chiltern walk in Central Bedfordshire are the Sundon Hills, steep rolling downlands affording fantastic views over the surrounding plain, out north to the Greensand Ridge, and east to the classic steep chalk escarpment of Sharpenhoe Clappers, which is passed through as well. At Sharpenhoe one of the largest Neolithic hill fort sites in the South East is walked through, with good views east to Barton Hills, followed by a steep descent into the plain below. Further fine views of Pegsdon Hills further east along the Chilterns follow from the route through rolling grassy fields to the quiet hill top lunch destination of Pulloxhill. The afternoon route is less energetic, but not without interest, and leads through the gently rolling plain to the finish through ancient Flitwick Wood into the centre of Flitwick.
