It’s barely a mile from St Peter’s Church in Martindale to the summit of Hallin Fell and back again. It’s a short and relatively straightforward climb too, with just 150m or so of ascent all the way to the top. Don’t be fooled though - you get a lot of value for the such a short walk.
I've been to Oeschinensee twice, and it wasn't enough. Once in summer, enveloped in grey cloud, and a second time in January, under a beautiful blue sky. It wasn't enough.
