I am almost exclusively a fly fisherman for Salmon and Sea Trout. However, I do occassionally foray into other types of fishing, and have an interest in all things to do with our sport.
I am sure there will be very good pike fishing within a reasonable driving distance from the Borgie. There are quite a few lochs that contain pike in the north of Scotland, and many of them hold very large specimens.
If you do a search on the web, I'm sure you will find some information(sutherland, pike, fishing, scotland, highlands, etc.).
