IronMan is correct in stating that this is off the beaten track; Anglezarke Moor is open access land and there are no continuous footpaths. It can be heavy going on the way here.
In answer to Stroller’s query, and further to Charles’s reply, there’s been no known excavation of Round Loaf. Some flints have been found on the surface over the years. There’s no point in visiting Bolton (or Manchester) museum as they have nothing from local, human prehistory on display whatsoever.
