Big lake Loch Ness. Did cycle round it one day when Wifey and sprogs went on neds for the afternoon at Borlum near Drumnadrochit. About 67 miles round, and with a puncture going up a steep bit.
Didn't see the monster but did see the replica of Drake's boat, the Golden Hind, sail up it one day.
Views on it and around it are spectacular. We took a 2 hour boat trip from Fort Augustus, but it didn't last long enough. Will have to go back one day.
