The Mason's Arms at Strawberry Bank is a gem of a pub with great food and beer, only a couple of miles from Ghyll Head.
I caught my first ever trout on the fly at Ghyll Head almost three years ago. A Kate McClaren worked then. I went back for a second visit earlier this year and caught some fresh stockies on pulled lures then went for the hard to reach fish rising in the middle and picked up a few on suspender buzzers and Hares Ear emergers. Very scenic fishery I'm sure you'll enjoy it.
Same trip I also fished High Newton and had a fantastic day on Black Buzzers. The water is deep and clear and they hit them hard. Always breezy up there, very exposed so if it's windy in the valley think twice. I'm itching to go back!
Good luck with the trip, make sure you post a report when you get back.
