We start at Church Farm, Aldbury. Extensive parking available with a cafe and toilets. The cafe is very popular with walkers and cyclists, so why not arrive early and enjoy a coffee and bacon roll to start the day off properly. We head out of the back of the village following a low contour around the base of Toms Hill, then footpaths and lanes towards Northchurch. Eventually we will pick up the Grand Union Canal near Cow Roast to bring us back to Tring Station. Returning to Church Farm via Stocks golf course. The walk is gently undulating with no major ups or downs.
