Part of a series which offers walkers a practical tool to walking in Snowdonia - clear directions, accurate linear measurements and compass bearings, including line drawings which have been composed from folk memories and recollections of oral historians. This title in the series describes ancient routes impressed on Snowdonia over the past 5000 years. Twenty-seven settlements that evolved during this immense timespan are described in outline. The earliest map of North Wales showing packhorse trails in 1795 is reproduced. The book also includes the first time publication of a late 18th-century drawing of packhorses by Simon De Koster, the original of which is in The National Library of Wales, Aberystwyth.
