From winter doubts to a 9-hour flow through reservoirs, moors, and edges

Date: 06 April 2026

📍Route: Clockwise - Heatherdene Carpark > Win Hill > Rowlee Pasture > Alport Castles > Ditch Clough > Howden Reservoir > Cold Side > Upper Derwent Reservoir > Little Howden Moor > Howden Dean > Lost Lad > Back Tor > Derwent Edge (Cakes of Bread, Dovestone Tor, Salt Cellar, White Tor, Wheel Stones, Whinstone Lee Tor) > Lead Hill > Ladybower Tor

📏Distance: 36.8 km

⬆️Ascent: 1,180 / 1300 m

⌛Time: 9 h

Weather: 12-15°C, sunny

Mood: Reflective, uplifting.

The Dambusters Challenge route takes you all the way around the 3 large reservoirs (Howden, Derwent and Ladybower) in the Upper Derwent Valley and leads you along dramatic gritstone edges, offering beautiful views along the way. It is described as a long distance walk of 23 miles. It is a challenging high level route in the Dark Peak area of the Peak District National Park. It is based on locations associated with the training runs undertaken during World War Two by Royal Air Force No. 617 Squadron (The Dambusters).

Filed Mentally Under “Maybe June”

Some routes sit in your OS mapped "Bookmarked" collection like a quiet warning.

The Dambuster Challenge was one of those. I mapped it out in winter, filed away for “maybe June ”when I would become a different human. Something long, committing, slightly intimidating. The kind of route you respect from a distance before you’re ready to step into it.

Every estimate pointed to 10 to 12 hours. And that kind of time on feet… it hadn’t happened since the bigger days in the Lakes last year. So I doubted myself as usual. Not doubt in ability, but doubt in duration.

The forecast was what changed everything, a rare good day finally lined up, bank holiday Monday, no plans, no excuses. Let's try it.

Ascent of Win Hill

Parked at Heatherdene carpark at Ladybower, £7.40 for 24 hours.

The day opened with the pull up Parkin Clough towards Win Hill, steep, rooted, a narrow forest line still holding onto patches of mud. Fresh legs made light work of it, but it set the tone early, this wouldn’t be a gentle warm-up.

And then 40-50 min later, something rare.

At the summit of Win Hill… no wind!?

After months of bracing against it, leaning into it, hearing it before seeing the tops, the stillness felt almost unnatural. A quiet summit, sunlit, calm.

The path through Parkin Clough woodland towards Win Hill

Woods and Rowlee Pasture

Instead of the familiar line turning left from Hope Cross, the route slipped right, into unknown forest. A descent all the way back towards reservoir level, then a climb again to Rowlee Pasture, much of it traced by narrow flagstones threading through the moor. The yo-yo of hiking I learned to love.

And then, a moment that cuts through the calm.

Two groups of walkers with dogs paused to pass each other right in front of me. One dog stepped off the stones.

Instantly, it sank!!!

Not slowly, not gradually, but straight down into the bog, its back legs swallowed deep enough to shock everyone watching. This was not a heavy dog but a border collie. The owner had to pull hard to free it.

It lasted seconds, but it stayed.

I couldn’t help thinking, if a heavier person stepped into that bog, where would they even go? It only reinforced my fear of bogs. don’t even have to experience it myself. I’ve seen the videos, and now I have a live memory too.

Alport Castles: A Promise for Another Day

Then came Alport Castles, believed to be the largest landslip in Britain.

Wild, broken, dramatic, a landscape that doesn’t belong to the gentle idea many have of the Peaks. The temptation to drop down and explore properly was quite strong, but this wasn’t a place to rush.

I admired from above and it became a promise instead, one to return and give it the time it deserves. Sometimes I surprise myself when I resist impulses.

Howden: Where the Day Opened Up

The route softened into Howden Reservoir, and somewhere between kilometre 14 and 22, everything clicked. This became my favourite part of the hike.

Paths next to woodlands. Still water reflecting a blue sky. Sunlight cutting through trees. Silence, broken only by birds. This was the heart of the day.

At Slippery Stones, the far edge of Howden reservoir, the loop turned. 20 km done. Five hours on foot, without stopping. And yet, no fatigue.

Just warmth from the sun, a steady rhythm, and the quiet sense that the day was giving more than it was taking. After all my recent hikes where I was battered by the weather I can finally fully enjoy the whole day. Oasis said it best in "Hello", how weather can either break your day or make it.

Into Solitude

From where Howden meets Upper Derwent Reservoir, the route climbed again, up onto Little Howden Moor.

No people. No wind. No noise. Sun beating down. Summer feels.

Second most favourite part of the day.

For 4 to 5 kilometres, it felt like the Lakes. A single line across the hillside, river dropping away to one side, rising ground to the other.

That same sense of space. Of walking for hours without interruption. Of being small in a wide, quiet landscape. The solitude. The kind of terrain that lets your mind drift north even when your feet are still in Derbyshire. I felt strangely happy while my mind was reminiscing and inventing alternate realities. I had a slight smile almost the whole time.

Derwent Edge and the Final Stretch

Derwent Edge followed and the stillness ended at Lost Lad.

The wind returned. Jacket on.

At Back Tor, the trig was touched again, not out of necessity, but out of habit. 27 km done. Still 10 to go. But by then, the distance didn’t feel heavy.

From there, the familiar drama of Derwent Edge unfolded, shaped stone after shaped stone, each with a name as strange as its form:

Cakes of Bread
Dovestone Tor
Salt Cellar
Wheel Stones
Whinstone Lee Tor
Lead Hill
Ladybower Tor

Nine Hours Later

And just like that, 9 hours passed.

37 kilometres. 1180 metres of ascent.

The longest day in the Peak District, done without sitting down once.

No real struggle. No breaking point. Just steady constant movement, good weather, and a body that never asked to stop.

🔍 Final Thoughts

At first, this was a challenge, Dambusters Challenge is the name after all.

But what really sticks with me isn’t the label, the kilometres, or the climbs. It’s the feeling I carried away from the day, walking through new unexplored areas, the sunshine warming my skin, the views stretching endlessly, and that quiet internal sense of being fully alive.

That combination of place and feeling is what defines the walk and what I remember most.
