Cwm Idwal Nature Reserve


AREA — 3.88km2, 398 hectar
HEIGHT — 373m, 1001m

In 1954, Cwm Idwal was designated as the first National Nature Reserve in Wales, and today it is a very popular attraction for a wide range of visitors.

The primary reason for designating Cwm Idwal as a National Nature Reserve was the unique geology found here. The second reason connects rare plants to the special geology.

The National Trust, Snowdonia National Park Authority and Natural Resources Wales work in partnership to manage Cwm Idwal.
