Come to thinki of it I can't remember if Skye gets a spring or autumn run - worth a bit of research perhaps, 'cos if tis a spring run then March might well put you in to a Salmon or Sea Trout !
Check with whatever hotel you are staying in, some of them have their own bits of river and salmon / sea trout fishing, and even if they don't they will usually know a local who does/
Plus which, as the rivers are so short (obviously, it being a tiddly island !) the fish are very clean and short run, estuary and up to the spawning redds in a day or two, so clean fresh and silver, no hanging about in stagnating pools going stale waiting for rain. Good luck.... and you sure you don't need a Ghillie ??? Or Valet ? I iron....
