A different and, for me, more interesting route over Allen Crags and Glaramara. The beauty of Langstrath makes it a much better walk in than the more mundane route from Seathwaite.
It’s a fairly long and strenuous walk. Navigation on Rosthwaite Fell can also be an issue, especially in the clag. One best left for a clear day, especially are the views are excellent.
There is some avoidable scrambling on Glaramara, and there are long pathless sections. That said, it’s a great walk and well worth the effort 🙂
