Garreg Lwyd

Rising above the Elan Valley, this prominent Central Wales moorland summit offers a sense of profound isolation. Its name, meaning 'Grey Stone', reflects the weathered gritstone outcrops scattered across its broad, grassy slopes. Reaching its high point provides a grand perspective over the expansive, wild plateaus of the Cambrian Mountains.

• •The name translates from Welsh as 'Grey Stone' or 'Grey Rock', a common descriptor in the Welsh uplands for summits marked by weathered scree or prominent boulders that break through the peat and grass.
• •It is frequently visited as part of a longer trek through the remote Elan Valley hills, often paired with the neighbouring Marilyn of Gorllwyn to the north or as a stepping stone towards the higher wildness of Drygarn Fawr.
• •The summit offers a specific, far-reaching view west over the blue waters of the Claerwen Reservoir, one of the massive Victorian engineering projects of the Elan Valley.
• •Its status as a Marilyn—a hill with at least 150 metres of prominence—ensures that despite its relatively modest height, it stands out as a significant island of high ground in the rolling Mid-Wales landscape.
