There's not a fishery as such at Glencoe any more - used to be, long time ago - but there is a fishery at
http://www.fortwilliam-chalets.co.uk/index.html based at Torlundy, just north of Fort William off the A82. Great setting.
However, there's simply loads of good fishing in the area and a visit to the Rod and Gun Shop in Fort William should be high on your list. I'd ask about fishing on Loch Lundavra, you used to be able to get a boat from Lundavra Farm. Nice loch in a yet another great setting and the last time I fished there (er...... 19 years ago
) there were plenty of lovely wild three to the pound brownies around with the occasional bigger fish to be had.
Or.... strike down through Glencoe and make for Loch Tulla.
