About

Swiss Valley in north Carmarthenshire is centred on a narrow valley that contains a stepped series of small reservoirs built to supply nearby settlements. Paths follow the water’s edge and climb into surrounding farmland, linking copses and hedgerows with lanes. The reservoirs sit in a compact basin and are used for short walks, cycling and informal birdwatching, with public access managed from nearby car parks and gates.

Llangennech lies a short distance from the valley and functions as a local service village for the surrounding farmland. The main street has shops, a primary school and sports pitches, and lanes radiate into fields and the lower slopes of the valley. Community activities and local clubs use village halls and playing fields, and footpaths lead directly from the settlement into the Swiss Valley reservoirs for day visits or longer rural routes.
