Know Before You Go
There are various walking routes to the erratics field starting at the nearby village of Austwick. See this website for a map. The walk up the hill is moderately steep, but you are rewarded with excellent views at the top. The site is a popular place for geology student field trips; if you continue walking north past the erratics you will come across some of the best examples of limestone pavement in the area. When you have walked back into Austwick do not miss a pint at the Game Cock Inn. Open fire, great beer, and good food.
