Moel yr Ogof

Moel yr Ogof is a mountain summit in the Moel Hebog range characterized by alternating bands of pillow basalt and green sandstone. The geological structure displays a large syncline that runs from northeast to southwest.

The mountain contains remains of an abandoned asbestos trial mine at its summit, where a small white asbestos seam was discovered but considered too small for commercial extraction. This failed mining attempt marks one of the site's geological investigations.

The Welsh name means 'hill of the cave', referring to a natural formation that shaped how locals identify this place. Visitors can observe this cave opening on the eastern side while walking the various routes.

Multiple walking routes lead to the summit from Beddgelert village or from Rhyd Ddu, with the main path ascending via Cwm Meillionen. Visitors should be prepared for changing weather conditions typical of this Welsh mountain region.

The eastern slope contains a cave linked to Owain Glyndwr, a medieval Welsh leader whose story remains alive in local tradition. This connection to Welsh history gives the location added interest for those curious about regional heritage.
