Twynwalter

Rising above the upper Swansea Valley near Glyntawe, this modest Fforest Fawr summit offers a quiet alternative to the busier neighbouring massifs. It features typical Welsh moorland terrain—unfenced, grassy, and occasionally boggy—providing a vantage point overlooking the Cray Reservoir and the dramatic Old Red Sandstone escarpments of the Black Mountain to the west.

• •The name is Welsh in origin, with 'Twyn' meaning a hillock or knoll, while 'Walter' is a personal name; such naming conventions in the Brecon Beacons often denote historical land boundaries or associations with medieval tenants of the Fforest Fawr hunting grounds.
• •From the summit, the view west is dominated by the spectacular 'Great Wall' of Fan Hir, the long sandstone escarpment that forms the eastern edge of the Black Mountain range.
• •Situated just north of the Beacons Way long-distance path, the hill overlooks the Haffes valley, where the river descends through a series of small waterfalls towards the Tawe.
• •At precisely 502 metres, it clears the half-kilometre mark with very little room to spare, yet remains blissfully ignored by the crowds heading for the more famous 'Fan' peaks nearby.
