About the garden

Owned by
Sue and Ian Mabberley

Nant-y-Bedd Garden is a 4 hectare (10 acre) wild and tame garden nestling in an imposing mature forest in the Black Mountains. This organic garden blends seamlessly into the special landscape of the Brecon Beacons National Park and has been developed over 40 years, taking cues from the environment and nature. It continually evolves, embracing the challenges of a mostly damp, cool and shady setting to advantage. 

We think it is somewhere a bit special, but don’t just take our word for it. Here is just a very small sample of our recent visitors’ comments: "Many gardens are described as ‘magical’ but Nant-y-Bedd truly is. I’ve never seen a garden so beautifully woven into a landscape." "Bursting with colour, imaginative and thoughtfully created: potager garden, exotic black ducks, evocative treehouse, river pathway, a welcoming Shepherd’s Hut, a Black Mountains version of an infinity pool, Sichuan peppercorn tree and self-service tea and coffee in a gorgeous geranium filled sunroom." "If I could create something half as beautiful as Sue’s potager I could die happy!" "Such a joy to wander though your magical garden, created with such a seemingly light touch and great sensitivity." "If you visit just one garden in Wales this year, make it this one!" "The calm and harmonious environment I know is only there as a result of hard work, single mindedness and dedication." "I arrived with the cares of the world on my shoulders; I left completely relaxed!"

And a final one from RHS legend Alan Titchmarsh: "If there is a more magical wild garden, I have yet to find it! Wonderful!" We couldn’t have put it better. Come and see for yourself!
