Hertford North to Ware and back

Easy leisurely walk from Hertford North Station through woods, past St Leonards Church with its Norman apse,  along the River Lea to Ware.  Either an early lunch stop or a coffee stop in Ware, returning along the New River,  past its source and back into Hertford.  It may be muddy in parts.   A hill to start with, then fairly flat and generally good paths although  a bit uneven along the New River. There are plenty of cafes in Ware for lunch or a snack, but if you prefer bring a packed lunch.
