From the car park go through the gate, fork left and take the second gate on the left to climb the steps and walk along the top of the dunes with the sea away to your right. Go past Sea View farm and a small parking area and continue beyond a white barred gate, forking right to reach the marshes. Go left and follow the clear track along the edge of the marshes.

At the far end of the dunes, join a rough lane across two successive bridges, then turn right on to the pavement of the coast road. After 100yds (91m) cross another bridge and turn right beside an unmade lane indicated 'Saltfleet Haven'. Follow the public footpath along the top of the flood defence all the way to the small car park among the dunes – and a bit further if you want to view the sandy bay and river mouth (tide permitting).

At the back of the small car park, and with your back to the Haven, go up the steps and take one of several faint paths through the dunes in order to pick up the wide track that runs just seawards of the vegetation-topped dunes (not along the actual water's edge). The strip of marshes is spread out to your right.

In just under 0.5 miles (800m), turn left up a concrete ramp by some evergreen trees and walk down Sea Lane past the caravan parks. Turn left at the end, then right after the Crown Inn into Pump Lane. At the far end follow the unmade track as it curves left between houses and, at the gap in the hedge, take the footbridge on the right for a path across fields.

Crossing another footbridge to emerge on the bend of Louth Road, turn left and, just after Hilltop Farm, turn right for a long field-edge public footpath.

At the far side go over a wooden footbridge near a house, then right and immediately left over a bridge to resume your field-edge route. Beyond a longer footbridge continue alongside Mar Dike until you switch banks nearing the far end to reach the road.

Turn left and walk down to the crossroads. Go straight over and along the drive opposite as far as Sea View farm. Turn right on the waymarked public footpath through the farmyard and field beyond, and continue on the clear path along the landward edge of the dunes to return to the car park.
