Exit the rear of the car park and turn right to the Chapel of St Mary Magdalen. Walk in front of the chapel, then turn left and continue downstream along the Thames Path, heading for Boveney Lock. Windsor Racecourse can be seen over on the Berkshire bank. Continue on the tow path, cross Boveney Ditch on a footbridge and bear immediately left at a path junction. The modern Windsor spur road can be seen over on the right. After 50 paces turn left over the footbridge, by the distinctive Sustrans milepost, and veer immediately right on a narrow dirt path. Skirt round the field, keeping the ditch hard by you on the right, and pass a row of houses on the far bank.

Bear left following the perimeter. Look for a waymarked footpath sign ahead (it may be partially hidden in a copse) and turn right to follow it between fields to a stile, which brings you back to Boveney Road. Turn right to follow the road across Dorney Common, towards Dorney village. Pass Wakehams, a timber-framed house with a well at the front. Away to the right is a fine view of Windsor Castle with its famous Round Tower. Keep left at the T-junction, cross a cattle grid and join the pavement. Walk through Dorney, keeping the Palmer Arms on your right. Bear left into Court Lane, follow the path parallel to the road and pass the entrance to Dorney Court. You soon reach the Church of St James the Less.

Continue on the path now on the left side of the lane, and when the road bends right, go straight ahead at the sign for Eton College Rowing Centre. Keep to the right-hand side of the drive and follow the path round to the right, by the low-level wooden waymarker, signed towards Maidenhead. The trail becomes the broad gravel Barge Path, popular with serious cyclists, so be alert as you are walking along here. This leads to the Thames Path.

Turn left here and follow the river, facing Bray Marina on the opposite bank. Further downstream the imposing cream facade of Bray film studios edges into view, its sweeping riverside lawns and weeping willows enhancing the elegant scene. Continue on the leafy Thames Path and you will soon catch sight of Oakley Court across the water on the opposite (Berkshire) bank of the river.

Beyond Oakley Court you'll see the cabin cruisers and gin palaces of Windsor Marina, and next to it lines of caravans and mobile homes overlooking the river. Through the trees on the Buckinghamshire bank is the outline of Eton College's new boathouse and its superb rowing lake, a star of the 2012 Olympics. To gain a closer view, briefly follow a path beside the river boathouse and slipway, go through a gate and walk towards the lake; and then retrace your steps to the Thames Path. On the opposite bank of the river is Windsor Race Course Yacht Basin and ahead now is the Chapel of St Mary Magdalen. Follow the path alongside the chapel to a kissing gate, and about 50yds (46m) beyond it reach a lane. With the Old Place opposite and an avenue of chestnut trees on the right, turn left and return to the car park.
