Tarren y Gesail, Mountain summit in Gwynedd, Wales
Tarren y Gesail is a mountain summit in Gwynedd rising to approximately 667 meters with a broad grassy ridge topped by a stone cairn and a surveying marker. The peak sits within Snowdonia National Park and forms part of the larger upland landscape of central Wales.
The mountain forms part of the ancient Cambrian Mountains, which developed through geological processes over millions of years in Wales. The region has been traversed by people for millennia and shaped the settlement patterns of the Welsh uplands.
The mountain stands within the boundaries of Snowdonia National Park, where Welsh language and traditions remain strong among local communities.
The mountain is accessible via multiple hiking paths, with the main route starting near Talyllyn Railway station and offering options for different fitness levels. Weather conditions change quickly in the mountains, so bringing waterproof clothing and sturdy footwear is essential year-round.
On clear days, views from the peak stretch southward toward Plynlimon and Cardigan Bay, while Cadair Idris dominates the northern horizon. This panoramic sweep across multiple peaks and coastal landscapes from a single vantage point is something many hikers in the region find surprising.
