From Martyr Worthy the waymarked Itchen Way crosses the river twice to loop through Easton. Back on the right bank the path passes through a tunnel under the M3 motorway to Abbots Worthy, before again crossing the Itchen to join the Three Castles Path (St. Swithun's way and King's Way continuing to Winchester on the right bank). Heading south the Itchen Way passes under the A34 before running parallel with the former route of the former Didcot, Newbury and Southampton Railway between the Winnall Moors nature reserve and the Winnall industrial estate. After a short section along roads it enters Winchester at Durngate. The route then passes along the river through the historic centre of Winchester before following the Itchen Navigation, again running parallel with the former railway past the foot of St. Catherine's Hill.
