Hi all, I had an amazing day doing this hike in August - it was originally supposed to be just Buttermere and Haystacks but I was so entranced by the heathery landscape on my way down from Haystacks that I missed the turn to head back to Buttermere and carried on to Fleetwith pike and descended to Buttermere from there.
https://www.walklakes.co.uk/walk_27.html is most of the route but I started from Buttermere so it's just this loop plus adding on Buttermere.
I would say that this was my favourite hike of all the ones I did in the Lake District due to the sheer variety and beauty. Plus it was much quieter than the likes of Helvellyn which I still loved and was so glad I did anticlockwise against the crowds.
Will add pics now
