Penvalla

Rising steeply above the quiet Manor Valley near Peebles, this prominent Southern Upland hill offers a rugged, grassy ascent. Though overshadowed by the higher Tweedsmuir Hills, its status as a Marilyn ensures a sense of isolation and rewarding views across the Glensax hills and north toward the distant Moorfoots.

• •The name is likely Cumbric in origin, reflecting the area's ancient British history. 'Pen' means head or summit, while the second element may relate to a wall or rampart (gwal), possibly referencing the nearby Iron Age fort on Chester Hill.
• •It is often climbed as part of a circuit from the Manor Valley, frequently paired with the neighbouring summits of Drumelzier Law and Pykestone Hill for a high-level traverse across the broad, peaty ridges.
• •From the summit, walkers are treated to a clear perspective of the Manor Water snaking through the valley below, with the distinctive triple peaks of the Eildon Hills usually visible to the east.
• •The hill sits in a landscape rich in archaeology; the well-preserved Chester Hill hillfort lies just to the east, indicating that these slopes have been inhabited and defended for over two millennia.
• •Despite being a Marilyn, Penvalla remains blissfully ignored by the crowds heading for the more famous peaks further north, meaning your only company at the top is likely to be a few unimpressed sheep.
