Reccied the "loop" (from the Holm Moss Mast to Laddow and back) for this one yesterday with my son and dog. Not done it before. Serious wind, rain and very cold. Very poor visibility (i.e. none) until the clouds lifted towards the end. Lost any hint of a path shortly after leaving the mast, but the N-S path on Tooleyshaw Moor was fairly easy to spot when we got back up the hill from Heyden Brook, even in the clag. From there the route down to Crowden is fairly easy to spot. Don't miss the right fork on Hey Moss just after the steep descent from Westend Moss.

There is a small track/trod back up to Bareholm Moss from Crowden, but we couldn't see any clear trod from there down to Crowden Great Brook or back up to the Pennine Way by Laddow: unless we missed one (quite possible) the quickest route would seem to be on a more westerly bearing than the one on the route map as it gets you up onto the Pennine Way faster, from where it is all runnable although technical in places.

Route from Black Hill back to the mast is easily missed (bearing needed initially) but easy to follow once found, although really, really boggy in places.

The many stream crossings were more like rivers after all the heavy rain and needed a bit of care, otherwise not really a problem.

I can see why it's classified as an AL - very, very tough going apart from the Pennine Way. Compass, map and good nav skills essential, especially in the fog.
