(S)The start (grid ref. SU763826) is the bridge over the Thames at eastern end of Hart Street (A4130). Cross the bridge to eastern bank and, following the signs, turn left almost immediately. This takes you down to the riverbank. Walk north with the river to your left. You soon reach Remenham with Fawley Court College across the river to your left. Continuing north you pass Temple Island before the river turns south-east to reach Hambleden Lock.
(1)Continuing on the Thames Path you reach Aston where the path turns inland (grid ref. SU786844). Turn right down the lane and proceed into Aston. Just past the road junction, turn left down the access to Holme Farm. Continue past this farm and following the clearly signed path continue until just before Lower Culham Farm, where you turn sharp left to reach the riverside again.
(2)The route ahead needs little description and Hurley Lock is the next key objective. Here turn left over the bridge, walk along the 'island' passing the locks. Ignore the footbridge immediately after the locks and continue ahead to reach another footbridge that allows you to regain the riverside path (grid ref. 828843) on the south side of the river.
(3)Continue for approximately 600 yards to turn left over a long footbridge (grid ref. SU834843) to gain the north bank of the river. All that remains is a pleasant mile and half walk into Marlow and the end of the walk.
