Head for the Bulbourne Valley to enjoy a picturesque waterside walk

THE Bulbourne Valley Walk is a circular walk that goes from Cow Roast, between Tring and Berkhamsted. There are two routes of differing lengths, both following the the Grand Union Canal towpath in this Area of Outstanding Natural Beauty.The longer of the two routes passes through the woodland of the National Trusts Ashridge Estate.

Close to the Cow Roast Inn lies the source of the River Bulbourne, once a full and fast flowing river. Like the other chalk streams in the Chilterns, the Bulbourne today is little more than a trickle.


From the Cow Roast Inn cross the road to the canal lock, taking great care of fast traffic, and go left along the canal towpath From Newground Road, the first road crossing, take the second track on the right after the railway bridge. On the far side of the field turn left and go up towards the wood.

For the shorter walk, turn right just before the wood, and over the stile into the next field. From here follow the footpath down to Norcott Court Farm and return to Cow Roast via the footbridge over the railway.

For the longer walk, go into the wood and up Toms Hill (a byway open to all traffic). After the Chiltern Hills Natural Mineral Water bottling site take the first footpath on the right into the National Trusts Ashridge estate.

Keep to the boundary of the wood until you see signs for the Icknield Way, then follow these south, skirting the edge of Northchurch Common.

Go down the lane past Norcott Court and over the railway, until you reach the canal. Turn right along the towpath to return to Cow Roast.
