There is a very nice flat walk around the lake after the more serious fell-walking. You can see Fleetwith Pike (but not the small white cross that occasioned the ascent up the ridge to the highest point you can see on the peak in the center). To the right you see the "sawtooth" which is Haystacks summit and the place of Innominate Tarn.
Walking South from Buttermere you see Fleetwith Pike on the left and Haystacks on the right. Fleetwith Pike is a non-intuitive approach to Haystacks, but a lovely one. You see, there was this tiny white cross trail marker which one can see on approaching Feetwith Pike....
