Loch Ness, Urquhart Castle & Cairngorm National Park Tour This tour takes a circle down Loch Ness, with time for visits at Urquhart Castle and Fort Augustus. Then we follow the Great Glen as far as the Commando Memorial and Spean Bridge, where we turn north, into the area where “Monarch of the Glen” was filmed. We return to Inverness through Cairngorm National Park, where several choices await. You could visit the Reindeer Paddock; the Highland Wildlife Park; Highland Folk Museum; or just walk in the forest at Rothiemurchus estate.
