Water doesn't get much more mysterious than this 23 mile stretch running through the Great Glen in the Highlands of Scotland.There's no better way to experience Loch Ness than by boat. Jacobite's award winning tours and cruises get you onto the water and into the heart of this iconic landscape. This is a whole lot more than simply sight-seeing. We've been running trips on and around Loch Ness for over 30 years and most of us live here.
