It can be walked in three weeks (or in shorter sections) and is suitable for experienced hillwalkers with sound navigational skills. The guide presents the route in 21 stages, offering comprehensive route description illustrated with OS 1:50,000 mapping and elevation profiles. Details of accommodation and facilities are provided, along with a helpful trek planner showing their distribution along the route: although the trail passes through remote areas, it is possible to stay under a roof every night - though camping is also a possibility, should you prefer.
Traversing the heartland of Wales, the challenging route crosses the Brecon Beacons, the Cambrian Mountains and Snowdonia, passing through two national parks and visiting many of the country's iconic summits, including Pen y Fan, Pumlumon, Cadair Idris and Snowdon itself.
There are background notes on Wales's history and geology and local points of interest, and a glossary of Welsh place-names, useful contacts and accommodation listings can be found in the appendices.
