After taking in part of the Ebury Trail, this walk joins the Chess Valley Walk, heading upstream and out of suburbia. Staying near the river, the route gains height only very gently, but sees it transformed into the chalk stream that cut its way between rolling hills. Following the full length of the valley it created points the way to Chesham, the town named for its source. Please bring packed lunch, pub stop at end of walk.
