East on the A180 until you enter Grimsby. At the second roundabout (Burger King/Little Chef on the left and McDonalds on the Right) take the 3rd exit onto Pyewipe Road Continue straight on until the next roundabout, and continue straight ahead again. The Market Hotel should be on your right as you come off the roundabout onto Yarborough Road. Keep following this road until the next roundabout at The Trawl Pub and turn left onto Little Coats Road, signposted A46 Lincoln. Keep going straight at both the mini roundabout and Bradley Crossroads roundabout, signposted Waltham. About 1m from this roundabout the turning for the woods will be on the right opposite a gate. If you reach a moderately sharp S bend you've gone to far. Once on the trail take the first path to the left and find somewhere to park, if you're the first then we should be along soon.
