The Environment

The Nant Gwrtheyrn valley

The whole of Llŷn has been designated and Area of Outstanding Natural Beauty and the whole village of Nant Gwrtheyrn has been registered (Grade II) by CADW (Welsh Historic Monuments) as Buildings of Special Architectural and Historical Importance.

However, buildings are not the only points of environmental interest at the Nant. The entire valley is one of the most beautiful locations in the whole of Wales and, at the same time, provides a home for all sorts of animals, birds and plants.



One of Europe’s rare birds – the chough - lives here and, the old quarry of Carreg y Llam nearby is one of North West Wales’ largest sea-bird colonies. A herd of wild goats lives on the surrounding slopes – they can often be seen sheltering in the village during bad weather.

Nant Gwrtheyrn achieved Lefel 2 in the Green Dragon Award Scheme in 2009. The recent developments have included significant investment in new technologies to minimise energy and water consumption and increased efforts to recycle waste.

The new technologies include a water purification plant which draws water from the valley stream and stores 50,000 litres on site to cope with any periods of dry weather.

New heating and hot water technologies include air source heat pumps which are four times efficient as a normal heating system and also a ground source heat pump for the caffi and neuadd y Nant and solar power for hot water in the cafe building.

Nant Gwrtheyrn is committed to reducing waste for landfill and is investigating how to recycle a maximum amount of the waste produced by the activities on site.
