The Centre for Alternative Technology (CAT) is an ideal setting for studying a wide range of subjects.

A ‘living laboratory’ with five decades of experience in sustainable issues, CAT can provide one easy package of teaching, hands-on learning, accommodation and catering.

Set in the Dyfi Biosphere in the foothills of the Eryri (Snowdonia) National Park, CAT offers students the opportunity to live and learn in an education centre like no other. Situated between the mountains and the sea in an area of rich political history and biodiversity, CAT is within easy reach of ancient industrial sites and the upland habitats of Cadair Idris and Plynlimon (Pumlumon Fawr).

Choose from ready-made or bespoke programmes for undergraduate and postgraduate students delivered by your own staff or by our expert tutors. Suitable for students of human geography, physical geography, environmental politics, ecology, environmental science, renewable energy engineering, architecture and green building materials and methods.
