Loch Lubnaig Callander Argyll & Bute
It may be small by Scottish standards, barely 5km long and only around 40m deep at its deepest point, but this wee gem is one of the nation’s prettiest lochs by some way. It's dead easy to get to as well, just north of Callender, and a handy stop off for those heading further north. It is dominated by two hulking mountains, Ben Ledi and Ben Vorlich, and surrounded by swathes of forest, and you can rent canoes, fish or just chill by the water’s edge. There are car parks and fishing spots, while cyclists or walkers can take in its whole length by following the off-road route that cuts through from Callander to Stratheyre.
