Known for its "bonnie, bonnie banks," Loch Lomond is Scotland's largest loch in terms of surface area, and its waters reflect the crags that surround it. The song "The Banks of Loch Lomond" is said to have been written by a Jacobite prisoner incarcerated in Carlisle, England.
On the western side of the loch, the A82 follows the shore for 31 miles to Crianlarich, passing picturesque Luss, which has a pier where you can hop aboard boats cruising along the loch, and Tarbert, the starting point for the Maid of the Loch. On the eastern side of the loch, take the A81 to Drymen, and from there the B837 signposted toward Balmaha, where you can hire a boat or take the ferry, to the island of Inchcailloch. Once you're there, a short walk takes you to the top of the hill and a spectacular view of the loch. Equally spectacular, but not as wet, is the view from Conic Hill near Balmaha. If you continue along the B837 beyond Rowardennan to where it ends at a car park, you can join the walkers at the beginning of the path up Ben Lomond. Don't underestimate this innocent looking hill; go equipped for sudden changes in the weather.
