Starting from Selwyn Hall car park in Box we follow the Macmillan Way beside the Bybrook River to Widdenham Farm. After skirting Monk's Wood/Colerne Park, we climb through woodland to Rudloe and on to the village of Box Hill. We continue towards Hazlebury Manor and meander through woodland and fields to Blue Vein, Henley and back to Box. This is a pleasant, varied walk with 1100 feet of climb over the whole route. There are plenty of good views. There is one short stretch of approx 20 feet where the ground is very muddy. Please wear suitable footwear!
