Visit CAT

Discover a hidden world, packed full of working examples of renewable energy, beautiful organic gardens, experimental green buildings and sustainably managed woodland habitats.

We confirm with a heavy heart the closure of CAT’s visitor centre to day visitors from 09 November 2023. It will remain open for students, educational group visits, events, and courses.

A full statement from CAT:

CAT is nestled in the stunning UNESCO Dyfi Biosphere on the edge of Eryri (Snowdonia) National Park, just 3 miles north of Machynlleth. Join us for an educational and immersive day out for all the family!

At CAT we believe in a positive future where we have learnt to live harmoniously with nature and tread lightly on the planet while enjoying the highest quality of life. Our Visitor Centre helps you explore that vision for the future and learn about ways to help achieve it.


Check this calendar for all the tours, talks and family events happening at CAT throughout the year.
