From the port in the Firth of Clyde, you are less than an hour from the rugged beginnings of Scotland’s famed Western Highlands. A key landmark of the region is Loch Lomond, the largest body of freshwater in Great Britain. Recently opened at its southern shore near the village of Balloch is the Sea Life Aquarium. Further up the loch, near Tarbet, sightseeing ships ply the deep blue waters below the peak of Ben Lomond (974 meters).
