Conditions on this route

We score every Lakeland Wainwright each morning on cloud, wind, rain and underfoot, and this route crosses 1 of them. The worst summit governs the verdict — a route is only as kind as its roughest top.

The walk, stage by stage

  1. 1

    Start → Great Whinscale (6.4 km, 378 m)

    Descent of about 181 m, then a climb of about 378 m, over 6.4 km.

    From the Devoke Water turning on the Birker Fell road, head out onto the vast, undulating expanse of Birker Fell. The defined path quickly becomes intermittent as you traverse the expansive, pathless moorland, forcing you to pick a weaving line through deep heather and tussock grass to reach the minor rocky outcrop of Great Whinscale.

    Waypoints

    Valley floor track, Birker Moor plateau, Great Whinscale summit.

    Decision point

    Rely heavily on compass bearings once you commit to the open moorland, as paths on Birker Moor frequently braid into misleading sheep trods or disappear entirely into the marsh. Use the subtle topographical rises to maintain your heading.

    Easy to get wrong

    The Birker Fell plateau acts as a massive sponge. It is exceptionally boggy, trackless in many places, and covered in energy-sapping terrain. The lack of distinct, towering landmarks makes this sweeping moorland highly disorientating when the clag drops, requiring intense navigational focus from the moment you leave the valley tracks.

    If you need to get off

    Retrace your compass bearing back off the moorland to the valley track. Do not attempt to drop blindly into the steep, wooded ravines that line the Eskdale and Duddon sides of the fell, as these are often craggy and impassable.

  2. 2

    Great Whinscale → Crook Crag (0.4 km, 35 m)

    Undulating section of about 0.4 km.

    Continue south-east across a short, marshy depression, weaving through the boggy pools to make the brief, straightforward pull up to the rocky top of Crook Crag.

    Waypoints

    Great Whinscale, moorland depression, Crook Crag summit.

    Decision point

    Crook Crag is visually obvious in good weather as a prominent rocky tor rising abruptly from the surrounding heather, serving as a perfect line-of-sight target.

    Easy to get wrong

    While incredibly short in distance, the ground between these crags is often completely saturated. It requires constant micro-navigation and hopping between grass tussocks to avoid sinking over your boots in the black peat.

    If you need to get off

    Abort the route and head north/north-west back across the moorland toward your ascent path, purposely skirting around the deeper mosses to the east.

  3. 3

    Crook Crag → Green Crag (0.6 km, 52 m)

    Undulating section of about 0.6 km.

    Drop slightly from Crook Crag and traverse another deeply rutted, wet saddle. The final approach requires a short, sharp scramble up steep, rocky tiers to attain the commanding, craggy summit of Green Crag.

    Waypoints

    Crook Crag, marshy saddle, Green Crag summit (489m).

    Decision point

    Green Crag is the highest and most prominent peak on the Birker Fell plateau; its dramatic rocky profile is a clear visual handrail for this short section.

    Easy to get wrong

    Green Crag is a fortress of rock erupting directly out of the bog. The rocks can be surprisingly greasy, and the way up the crag tiers needs hands for a few steps, a contrast with the moorland slog before it.

    If you need to get off

    If the final rocky pull of Green Crag is too slippery or intimidating in wet weather, simply bypass the summit rock to the west and begin your return leg across the moorland.

  4. 4

    Green Crag → Broad Crag - Birker Fell (1.3 km, 27 m)

    Descent of about 110 m over 1.3 km.

    Carefully down-climb from Green Crag's rocky summit, heading south-east at first, then swing round south-west and west into the notoriously wet interior of the moor. You must pick a tortuous, weaving line through the trackless expanse of Foxbield Moss and White Moss, aiming for the modest rocky rise of Broad Crag.

    Waypoints

    Green Crag descent, Foxbield Moss / White Moss, Broad Crag summit.

    Decision point

    With no distinct paths and a featureless plateau, you must rely entirely on a compass bearing aimed at Broad Crag, accepting that you will have to zigzag extensively to avoid the worst of the bogs while maintaining your general heading.

    Easy to get wrong

    This section crosses some of the most infamous, boot-swallowing peat bogs in the Lake District. There is no path, and straight-line navigation is physically impossible; you must constantly detour around deep black pools and marshy ground, making the short distance feel twice as long and incredibly tiring on the legs.

    If you need to get off

    You are in the desolate center of the moor; the usual escape is to push through the bogs to Broad Crag and Great Crag to pick up the established descent routes, rather than trying to bail northwards into pathless, steeply plunging bracken.

  5. 5

    Broad Crag - Birker Fell → Birker Fell - Great Crag (0.9 km, 16 m)

    Descent of about 49 m over 0.9 km.

    Leave Broad Crag and continue the westerly traverse across the undulating, heather-clad moor. The ground here becomes slightly firmer but remains pathless as you link up the final rocky tor of Great Crag.

    Waypoints

    Broad Crag, Birker moorland traverse, Great Crag summit.

    Decision point

    Great Crag stands out as the final distinct rocky bump on this section of the plateau. Keep it in your sights as a bearing point while you pick the driest, most direct line through the heather.

    Easy to get wrong

    The terrain remains incredibly rough, with hidden holes between tussocks and thick heather concealing uneven ground, presenting a constant trip or twisted ankle hazard for tired legs.

    If you need to get off

    No way off this moor has been checked for this guide. Great Crag, ahead, leads to the route's own descent, and going back over the bogs is the way you know: judge which from where you are.

  6. Birker Fell - Great Crag → Finish (2.5 km, 37 m)

    Descent of about 83 m over 2.5 km.

    Depart Great Crag, heading steadily downhill off the moorland plateau. Pick up the faint grassy trods that gradually coalesce into a more defined track, winding down through the bracken and rough pastures to return to the valley road and your starting point.

    Waypoints

    Great Crag, moorland edge, descent track, valley road, finish point.

    Decision point

    Once you crest the edge of the plateau, the valley floor and the ribbon of the road below provide a visual handrail; keep to the route's own track down, rather than aiming across the bracken for a gate or stile.

    Easy to get wrong

    The initial drop off the moor can be steep and slippery in places. In summer, the lower slopes are often choked with head-high bracken that can completely obscure the faint path and conceal rocks, making navigation frustrating just as you near the finish.

    If you need to get off

    This is the final descent. Take your time through the thick bracken, ensure you do not blindly drop into steep ravines cut by the descending becks, and stick to the gentler grassy spurs leading down to the valley road.

In the order you walk them — the same numbers the elevation profile, the stage notes and the pacing table use.

Keep to the built line. The notes on this route mention eroded or braided ground. Where it is mud or standing water, walk through the puddle rather than round it, stay on the pitched stone even where it is a staircase you would rather not use, take the zig-zags the long way, leave loose stones and cross-drains where they lie, and build no cairns. Deep or moving water is a different question — turn back or take the safest way past rather than wade for the sake of a path. Fix the Fells’ volunteers keep these paths: what a metre costs, and how to give a day or a few pounds.

More about this walk

From the Birker Fell road, at the turning for Devoke Water, it heads north-north-east across open, boggy moor to a cluster of five rocky little summits: Great Whinscale, Crook Crag, then Green Crag, the Wainwright and high point of the day, before Broad Crag and Great Crag on Birker Fell. About 12 km but genuinely rough underfoot, with a big view over the Duddon, Eskdale and out to the sea.

Park on the verge at the Devoke Water turning on the Birker Fell road between Ulpha and Eskdale — a narrow, remote fell road, so come prepared and don't rely on a phone signal. It's a long walk in across open moor to the first top.

Conditions and timing

Best season Best after a dry spell and in clear weather — Birker Moor is rough, boggy and pathless in places, and easy to misread in low cloud.

Check live conditions in the “From the fells” panel, on MWIS (opens in new tab) and the Met Office mountain forecast (opens in new tab) before you set off.

When the sun reaches the tops

Not sunrise — the moment the sun clears the skyline from that summit, which on a fell with high ground to its east can be a good deal later.

  • Green Crag — in late March the sun reaches it around 06:30, about a quarter of an hour later. In late September, about 07:15. It waits longest in midsummer — about half an hour after sunrise.
How to read these times

The two equinoxes are shown because they fall in the walking season, and late December too wherever a top keeps you waiting then; the clock gap between the equinoxes is British Summer Time, not the hill. Rounded to the nearest quarter hour and meant as a general idea, not a schedule.

Modelled from a 30 m elevation model against each summit’s own skyline — the same figures the fell pages carry, never observed. Cloud is not in it.

If the parking is full

There is no real plan B here. Every place we know beside this route serves the same walks and sits close together, so expect them to fill on the same mornings. Worth starting early, or having a different walk in mind before you set off.

  • Devoke Water turning, Birker Fell road (verge) — at the start
  • Rough Crag Birker Moor (verge, south) — a 280 m walk to the start

We never say whether anywhere has spaces today. Walks to the line are measured along mapped paths (OpenStreetMap), not in a straight line. How we choose these places.

No signal when you get there? RoutePark keeps this list on your phone: choose this walk’s GPX at home, keep it, and it opens offline.

Buses

No bus we hold serves this start. The nearest stop we hold is the 505 at Coniston, outside The Ruskin Centre, 17.3 km away on foot: a walk of its own, not a way to the start.

Toilets and refreshments

The essentials

  • Arrival Rough free verge parking at the Devoke Water turning on the Birker Fell road, beside the start. 36 m in a straight line, not a walking distance. (our parking map, from OpenStreetMap, checked 2 August 2026)
  • Toilets No toilets are mapped within 250 m of the start. (OpenStreetMap, as mapped on 13 September 2026, checked 13 September 2026)
  • Refreshments No café or pub is mapped within 250 m of the start: bring what you need. (OpenStreetMap, as mapped on 13 September 2026, checked 13 September 2026)
  • Limitation A largely trackless round across open, boggy moor: the path soon becomes intermittent and you pick your own line between the tops. (our route notes (this route's own warnings), checked 28 September 2026)

No mapped drinking water or shelter on this route — that doesn’t mean there is none, and never drink untreated from a beck. (Facilities data © OpenStreetMap contributors.)

Five independent axes, not one score. This route has not been walked yet, so none of them was set on the ground: one of the five is our judgement from the map and the route’s record, and the rest are computed from the recorded track and the map, which measures the line rather than surveying the ground.

How we grade: each axis is Easy, Moderate, Hard or Severe, and a route between two bands takes the higher one. Length: under 8 km, 8–14 km, 14–20 km, over 20 km. Steepness, the steepest 500 m of the track: under 15%, 15–25%, 25–35%, over 35%. Terrain, navigation and exposure are judged rather than measured, and each note says why. How we grade.

Access & barriers

Can a dog, a buggy or dodgy knees manage this route?

Dog
Mostly gates
Buggy
Not buggy-able
Knees
No steep descent mapped
  • Buggy: Stiles or rough going on the route.
  • Knees: No sustained steep descent in the track’s height model (steepest 250 m about 17%). Steps, wet rock and the surface underfoot are not assessed; your own knees still matter.

With a dog

Hardest for a dog here: stiles and gates. The steepest stretch is a sustained climb of about 22% around the 4.3 km mark.

  • Stiles and gates: A stile of unmapped type at 3.0 km — a dog may need lifting over. (OpenStreetMap, mapped as of 9 July 2026)
  • Rock and scrambling: Hands for a few steps: Green Crag's summit tiers, and the way off it (km 6.8–7.4). Ground underfoot: Hard – our judgement from the map and the route’s record; not walked yet. Mostly good mountain path.
  • Drops and exposed ground: Not assessed on the ground; the map suggests Moderate. Graded from slope only (~25% max); treat exposure as unverified.
  • Ways off early: None recorded for this route.
  • Livestock, shade and water: Not recorded for this route yet. We never call a stream safe for a dog to drink, so carry enough for both of you. The lead rules, and what to do around cattle, are on dogs on the fells.

On the line: 7 gates · 1 stile (type unmapped)
