The 'seat' seems to have taken a bit of a battering. Here's what it looked like when I was up there in July last year ...
It's a great walk to do from Hardraw. I just followed the Pennine Way up to Great Shunner Fell, then down to the summit of the Buttertubs Pass, followed by the short climb up to Lovely Seat. From there, it's a pathless walk across Abbotside Common before dropping down into Sedbusk and a short walk back to Hardraw.
A great little walk ...
