I started the walk from Market Weighton where I finished phase 2 last week. I had revisited the beautiful Rifle Butts Quarry Nature Reserve and proceeded to Goodmanham. This phase is also well marked with signposts and goes through pretty little villages and a lot of wheat fields. During the walk between Nunburnholme and Millington I could see the whole Vale of York and the huge power station etc.
