Derwent Edge is one of the numerous gritstone edges that form a near-unbroken line along the northeast of the Peak District. As with all the edges, it’s a popular spot for walkers, climbers and mountain bikers who all make the most of the unique countryside of the Dark Peak.
We parked in the Fairholmes car park after driving along the length of Ladybower Reservoir’s northern arm, along the route we’d be using later in the day. After getting ready, we walked the short distance to the foot of the iconic Derwent Dam, which holds back the Derwent Reservoir.

The Derwent Dam is a huge, solid masonry structure, built in the early 1900s to create the reservoir that supplies water to Sheffield and the East Midlands. It struck a resemblance to the Mohne Dam in Germany, so much so that 617 Squadron (the Dambusters) practised low-level flight over the Derwent Reservoir. In the dead of night, the pilots were expected to fly just 20m above the water, aided by a pair of strategically placed spotlights underside the aircraft.

We climbed up alongside the dam to follow the access road along the reservoir’s edge. It’s easy stroll of a couple of miles which leads to Abbey Tip Plantation, close to the Howden Dam. Unlike the Derwent Dam, the Howden Dam was overflowing when we visited – it is designed in such a way to allow water to spill over and flow down the dam face.

A stony track leads up the moor, crossing the head of a stream at Greystones Moss before a final, fairly steep pull up onto Lost Lad., a bare, conical hill prior to the main height of Derwent Edge. Lost Lad actually refers to the cairn that marks the summit – reference to the legend about a local shepherd boy.

According to the legend, the boy became lost on the moors in a blizzard and died. His body was found the following spring by a passing shepherd and nearby were the words “Lost Lad” written on a rock. An accompanying toposcope describes the 360-degree view – though much our ours was shrouded by cloud.

Back Tor – the starting point of our traverse of Derwent Edge – is a short distance south-east and the clouds parted long enough for us to get a good view of it. A trig pillar marks the highest point.

Derwent Edge is notable for the numerous gritstone tors that are evenly spread along its length, each given a name based on their unusual shapes. From north to south the following can be found; Cakes of Bread, resembling a pile of bread cakes (or bread rolls), the Salt Cellar, looking similar to like a salt grinder and the Wheel Stones (otherwise known as the Coach and Horses) which, when viewed with a little imagination, looks like a stagecoach and horses.
The real highlight of the edge is Dovestone Tor, the most significant of all the outcrops on the ridge, located around half way.

Hurkling Stones (and its commanding view of Ladybower) is the final landmark before we descended down to the A57, crossing the reservoir along the impressive arched road bridge. Ahead is a two-mile tramp along the shores of Ladybower, using the permissive footpath that leads back to Fairholmes.

Despite the cloud and the wind, this was a very enjoyable walk. Derwent Edge, though popular, still presents an opportunity to escape the crowds gathered on Stanage Edge or Kinder Scout and is no less interesting. The magnificent views and interesting rock tors make this one of the best walks in the Ladybower area.
