Stone Arthur, Great Rigg and Alcock Tarn

So we visited Lancaster the day before and arrived in the Lakes to stay in the old Thorney How youth hostel in Grasmere, a place big enough for the 16 of us on our yearly family holiday north. I’m not certain how many more of these we will get as the kids grow up (mine are 19 and 17 now!!) and we have been coming now for 18 years, but they are the best and both my two love this holiday. This year they drove themselves, well dad was behind them most of the way, tutting at the unnecessary lane changes and lack of signalling on occasions 😂. We all arrived safely and planned our outings for the week, our first one was the next day, a walk up to Great Rigg via Stone Arthur, returning along the ridge to Nab Scar before dropping to Alcock Tarn and back into Grasmere. Alcock Tarn was a first for me and it was nice to complete this round which added 4 more fells for Linda and the boys to their tally. Apart from the initial steep climb to Stone Arthur it is a good route with great views to the west throughout. The ridge back down from Great Rigg is a superb path, undulating and with views out along the Rydal valley, through Ambleside and on to Windermere. Next we turned on to the path that slants down to Alcock Tarn, through the bracken, popping out by the walls that enclose this area. The tarn sits nestled below Heron Pike on a shelf, above the steep ground falling to Grasmere, reeds have taken over a little across the water but it is a lovely spot to sit if you have time. We didn’t and if anything we were behind after a late start and needed to get a wriggle on for tea, which we made. A fine walk to start to week and one from the door which would become a theme as we only drove for one walk during our stay

Thorney How and our weekly stay. Its one of the few places big enough to take the 16 of us
Just at the end of the path you have views to Seat Sandal to the left, Firfield is in the middle and Stone Arthur is behind the tree to the right
Helm Crag as we cross the A591 to head up to Stone Arthur
Most of the way up tot Stone Arthur and we are huffing and puffing up the steep climb. Grasmere below
Stone Arthur summit with Grasmere below and the Coniston range back middle
Walking up towards Great Rigg, its a rolling ridge with rocky outcrops to negotiate. The major climb is done by the time you get to Stone Arthur so this isn’t too bad
Stunning views west and dozens of fells in views
On to Great Rigg summit and looking up to Fairfield
The other way with Ryudal valley to the left, the ridge to Heron Pike ahead and Windermere at the back. Infact you can see 3 other waters from here with Esthwaite Water and Coniston Water left to right and Grasemere down to the right
Great Rigg looking west, to the left of the summit cairn is Great Gable, Pillar and the High Stile ridge.
The Coniston range with the Crinkle Crags and Bowfell running left to right across the middle of the phot and on to the Scafell massif
Looking up to Rydal Head and part of the Fairfield horseshoe
Lovely views to Ambleside and Windermere
Walking to Heron Pike

More of the Fairfield horseshoe from Heron Pike, with Rydal Fell nearest to me
Nab Scar is next down there and sun breaks out across Ambleside
Nab Scar and Grasmere
Nab Scar and our next route, Alcock Tarn is down that way somewhere. The central fells dominate the background
Alcock Tarn
Stone Arthur and the route up to Great Rigg, as you can see from here its a steep ascent up to Stone Arthur through the bracken paths
And to finish a view to Helm Crag and the Central fells, the edge of Grasmere on the left. I took no more photos from here as we sped back for tea. A great walk and a great start to out week up here
