Organig Parc in Carnguwch, Wales

You won’t have to sacrifice style for sustainability at this rural retreat in Wales. Instead of cookie-cutter rooms, guests stay in charming holiday cottages that previously served as horse stables in the 1880s, and have since undergone extension renovation (using locally-sourced materials, of course).

Even better—the property sources its water from the nearby mountain spring, fuels its stoves from fallen trees, and ensures that all waste food is recycled and composted to fertilise the farm.
