Rhos Dirion

Perched on the long, grassy ridge of the Black Mountains, Rhos Dirion is a high-altitude peat bog masquerading as a summit. It offers panoramic views of the Vale of Ewyas, provided you haven't vanished knee-deep into the dark, slurping sludge of the plateau.

• •It marks a significant point on the high ridge between the Vale of Ewyas and the Grwyne Fawr reservoir, serving as a historic boundary between Powys and Monmouthshire.
• •The name translates from Welsh as 'fair moor', which is an optimistic bit of marketing for a landscape dominated by wind-scoured heather and erosion scars.
• •At 713 meters, it is classified as a Hewitt, making it one of the select peaks in England and Wales to exceed the magic two-thousand-foot mark.
• •The summit is marked by a lone trig pillar, which frequently serves as the only dry island in a sea of black peat hags during a typical Welsh downpour.
• •Navigation here is a breeze until the mist rolls in, at which point every peat hag starts looking like a landmark and you'll find yourself apologizing to a particularly stoic sheep for your total lack of direction.
