These maps normally cover an area of about 18 miles by 12 miles and are especially good at showing railways, roads and canals, and at giving a broad view of a wider area. Each includes an introduction and a more detailed map of a small town or village.

This Inch to the Mile map covers the south part of the Llyn Peninsula. Sheets 133 and 134 are included side-by-side for convenience. Coverage stretches from Bardsey Island eastward to Afon-Wen Junction, including Bardsey Sound, Aberdaron Bay, Porth Neigwl or Hell's Mouth, and St Tudwall's Road. The only town on the map is Pwllheli, where features include the Pwllheli & Llanbedrog Tramway. On the reverse is a section of Caernarvonshire Sheet 43.16, showing Aberdaron, still a tiny seaside resort, in 1914.

It is not possible to list the many hamlets, farmsteads and other topographical features shown on these maps. However, you might find it useful if we here list the majority of the principal villages and church parishes that are included on this map.
