From Fiveways, walk along Eastcote Road past the allotments on your left and where the road swings right, continue straight ahead on Tiffield Road, past Gayton Wilds House, where the road bears right and crosses Gayton Wilds. Just before the bridge over the disused railway, on your right is the entrance to Tiffield Pocket Park, the John Mawby Trail.

Go through the wooden gate and pause to study the magnificent and informative notice board. It tells you that this is a linear park, just over one kilometre in length, following the track of the old Northampton to Banbury railway line that was constructed in the late 1860's and abandoned in the 1960's. It has pictures of the flora and fauna that inhabit the park, such as the common spotted orchid, early purple orchid, great spotted woodpeckers, jays and barn owls. There is also a map showing points of interest along the way, such as the pond, which is visited by a kingfisher, is home to a colony of pond snails, as well as grass snakes, frogs, stoats, muntjac, dragonflies, damselflies and butterflies.

To your left are steps and a hand rail to guide you down the steep bank and onto the path below. When you reach the path, turn right, leaving behind you the massive, high brick arch of the road bridge. Straight ahead as far as you can see, runs the former rail track, now returned to nature as a rustic footpath, beneath a canopy of trees. Follow the path to Tiffield, stopping for a few moments to sit on the rough log seat that overlooks the pond on your right.

You reach a playing field on your left, known as Claydon's Field, at which point you leave the park through the wooden gate, walk diagonally across the field to the far corner, where you exit onto Gayton Road. Turn right and walk past the remains of the old rail bridge, where the former railway line crossed over the sunken road. Shortly after the gates of 'The Folly', on your left, the road turns sharply left, but you walk straight ahead onto the bridleway - there is an arrow marker on the telegraph pole - which leads uphill to Eastcote Road.

The bottom and top ends of the bridleway are narrow and usually grassy and firm, but the middle stretch widens out, is churned up by horses' hooves and is very muddy for much of the year. When you emerge onto Eastcote Road, continue straight ahead in the direction of Gayton and after about 30 yards, turn right onto a byway, which leads, almost in a straight line, with the hedge to your left, back to Gayton Wilds. You reach the road just before the entrance to the Pocket Park. Turn left and walk back to Gayton.

For a shorter walk, comprising the 2 ¼ mile circuit starting at the entrance to the Pocket Park, you can drive and park off the road at the start of the byway, a few yards before the gate leading into the pocket park.
