⚠️ Warnings: Access: The summits of The Benn (Sippling Crag), Castle Crag (Shoulthwalte) and Great How (Thirlmere) lie outside mapped CRoW open-access land. That records no statutory right of access — it is not a statement that access is forbidden, and permissive access is not recorded in that layer. This ground is above Thirlmere, a working reservoir managed by United Utilities, whose car parks at Legburthwaite and Swirls we list under parking. This line is computed rather than walked, so treat the access as unchecked and look for the courteous way through — how we work this out.

On the hill: terrain and water on Great How (Thirlmere)

Terrain & access

A 333 m top with a mapped path to within about 38 m of the summit. The summit is not on CRoW open access land, and the direct approach crosses land that is neither access land nor a right of way — there may be no public right to the top, so check access before you go.

Computed from open data, not walked — pathless ground needs confident navigation, and mapped paths, barriers and access boundaries can be incomplete. Data © OpenStreetMap contributors (via Overpass); Natural England CRoW Access Land; DoBIH; Copernicus GLO-30. See the terrain & access report for how this is worked out across all 144 fells.

Access on Great How (Thirlmere)

Access: Great How (Thirlmere) stands on United Utilities (Thirlmere estate)’s land, which the landowner manages for public access with permissive paths. This is invited access, not open-access land — the estate can close or re-route paths (storm damage and forestry work are common reasons), so check United Utilities (Thirlmere estate)’s current information before travelling. (Source: UU permissive estate; made path to summit, accessed 2026-07-29.)

Closures and re-routes are announced by the landowner, not on the national map.

How we worked this out

Summit and approach positions are tested against Natural England’s CRoW Act 2000 access layer; rights of way and wall or fence detail come from OpenStreetMap. Both are open datasets with known gaps — in our own survey only 4 of 23 wall and fence crossings had a stile or gate mapped within 150 m — so absence of a mapped feature never means absence of a real one. Nothing here is field-verified unless marked, and none of it is legal advice. How we checked 378 fells.

Places to stay near this fell

Fornside Farm Cottages guest house

about 1.1 km from the start, in a straight line

Ranked first on usefulness, not distance. It answers more of a walking family's questions than anything else in the valley: four separate self-catering units sleeping 4 or 6, an EV charger, dogs in two of the four, a private farm trail, and walks from the door onto the Helvellyn range the three routes climb. It is also 1.12 km from the start, so the tiebreak never had to be used.

The four cottages are converted 17th-century barns adjoining a grade II listed farmhouse, heated by a ground source heat pump part-powered by solar panels — and there is a private farm trail through the woods and fields for guests.

  • Family rooms “Rigg Barn was converted from a detached bank barn and sleeps up to six people.”
  • Parking “You can charge your electric vehicle on our PodPoint car charger, available exclusively for our guests.”
  • Children “We have just returned from a week in Swaledale Garth with our toddler.”

Dale Head Hall Lakeside Hotel hotel

about 2.1 km from the start, in a straight line

The only serviced hotel inside two and a half kilometres of the start, and the only property in the cluster offering rooms on the ground floor — which matters to anyone who has just come down Sticks Pass on tired knees, and to a family who would rather not carry a sleeping child upstairs. Several rooms are explicitly convertible to family use with extra single beds.

A 16th-century hall standing alone on the shore of Thirlmere inside a designated red squirrel reserve, with Helvellyn directly behind it; the site publishes its front door as the what3words location CRACKS.DIAMOND.RESPECTED.

  • Family rooms “A warm, traditionally designed family room, with one double and two single beds. Overlooking the back of the hotel.”
  • Evening meal “Why not enjoy a trip out to nearby Keswick for the day before coming back and enjoying a delicious bar meal.”
  • Children “This room can accommodate two extra single beds for a family.”
