On my BG last weekend we went round the back of the tarn -there is a stream to fill up here if you are short of water -then from the hause up and over the wall and climbed to the right of it -then coming down we just used the eroded zig zags and it seemed to work well -on the descent to Dunmail I gained 10 minutes on the schedule by going straight off the 'nose' slightly right heading for the north end of Steel Fell - if you want any more route choices let me know - what you need most is weather like we had last Saturday - I would not have got round this weekend!
