NY4023913381 Assuming you're starting from Cow Bridge car park, cross the A592 with care and take the pavement south-east, across the floodplain. Take the Hartsop turnoff and go up the lane through the hamlet. There's another car park here, which is worth knowing about if Cow Bridge is full.

NY4150212872 After a few minutes, the path forks. We take the left fork, contouring gently to the pumping house. (Note that the main bridleway drops down to the right, to cross the beck before the haul up to Hayeswater)

NY4212813051 At the pumping house, the nature of the route changes completely, becoming a pathless pull up the side of Calfgate Gill. Don't worry, though - it's only a brief pull.

NY4211413723 At the top, you'll gain a tussocky plateau, which is technically the col between Brock Crags and Rest Dodd. In high summer, this place is a riot of waving cotton-grass, like a crowd holding lighters aloft at a gig. Looking south from here, Gray Crag is seen as a sensational cross-section, splitting Hayeswater from the trench of Pasture Beck.Head west to the summit of Brock Crags, then retrace your steps to gain the main highway between Boredale Hause and High Street.

NY4211113923 Follow this north northwest, skirting the basin of Angle Tarn. This makes a pleasant spot to dunk, especially as it offers the opportunity to swim out to islands. A note of caution, though: the Canada geese are not especially fastidious with their toileting, and attempts to train them to bury their waste with trowels have proved fruitless. This may take the edge off an otherwise idyllic experience.

NY4150614573 At the northern end of the tarn basin, switch to Explorer Mode and head up the rocky tors on your right. It now becomes clear why Angletarn Pikes is always in the plural. When you've sated your curiosity, drop back down to the main path again and follow this on a broadly north-northwest bearing to Boredale Hause.

NY4064115660 Note that the hause is the confluence of no fewer than six tracks, so don't go astray in mist. Head south-southwest and this soon develops into a fine shelving descent at a good gradient. The views over Patterdale from here are eye-wateringly beautiful. The path soon levels off and keeps going south, along the edge of the floodplain.

NY4068314093 Just before the lovely cascades of Angle Tarn Beck, the path forks. Either way will get you back to Hartsop but the right fork is the bridleway and is slightly quicker.
