Where was Iolo: The Last Wilderness of Wales filmed?

This series was filmed in the Cambrian Mountains, an area of midland Wales including parts of Powys, Ceredigion and Carmarthenshire.

“People will be amazed at the diversity of habitats and species in the Cambrian Mountains,” says Iolo Williams. “Whilst most tourists go to the Brecon Beacons, Snowdonia or the coast, few realise that they are missing out on Wales’ hidden gem. It was a real pleasure for me to reacquaint myself with wildlife that, in some instances, I hadn’t seen since my youth.”

Historically, the Cambrian Mountains was used to describe much of upland Wales, but has become increasingly localised to central Wales.

During the 1960s and 1970s, it was proposed as a National Park but this was rejected in 1973.

There are a number of nature reserves, Sites of Special Scientific Interest, Special Protection Areas, and a Special Areas of Conservation in the Cambrian Mountains.

Many rivers have their sources in the Cambrian Mountains including the Severn, Wye, Teifi and Ystwyth.
