Manod Mawr lies in the heart of the slate quarrying district of Blaenau Ffestiniog. It has two summits only 3 metres different in height. The higher, southern top, at 661 metres, is rounded and grassy but the northern top has been almost entirely eaten away by open-cast quarrying, still operating today. Manod Mawr’s main claim to fame is that the UK’s art treasures were stored in one of its caverns during WWII. Below the flanks of the mountain lies a tranquil lake, Llyn y Manod, while alongside it runs the infant Afon Teigl. Our walk today will cross fields and follow tracks and rough paths, visiting the lake, the southern peak and a ridge above the beautiful Cwm Teigl. Weather permitting you can expect superb 360° views from the top!
