A guidebook to 30 day walks in Carmarthenshire in south Wales, including parts of the Bannau Brycheiniog (Brecon Beacons) National Park and the Carmarthenshire Coast Path. The walks are mostly circular and vary in difficulty, from short, easy walks to more challenging routes in open country, with something for all levels of experience and fitness.

The walks range from 5–17km (3–11 miles) in length and take between 2 and 7 hours to complete. They are organised into six geographical areas covering the northwest of the county, the central region, the Cambrian Mountains, Y Mynydd Du (the Black Mountain), and Carmarthen Bay east and west.
