drive down the a22 towards eastbourne till you come to a big f**k off roundabout, It's huge (and has a filter left and two lanes forward as you come to it), go right round it and there's a service station on the left, orrrr go m23, a23, a27 to eastbourne, to a set of traffic lights at a tee junction, the road bears left at the side of these, (eastbourne filter off to the lights), take the left, to a big f**k off roundabout and it's on the left. That's the polegate meet point. Cuckmere, head for the coast road between eastbourne and brighton, if coming from eastbourne, just drive along it. There's a river on the left as you drop downa large hill, you'll go over a single track bridge, pub in front, car park left. From brighton just stick on the coast road and follow it till you go through a town called seaford, you'll see the river to the right as you drop down a large hill, pub and bridge at the bottom. (There's a 90 deg bend onto the bridge and the car park is on the brighton side).
