Loch Lomond is one of my favourite parts of Scotland. On a sunny day it is perfect for a drive around the water, stopping in at the villages and small towns along the way.
Best of all is the climb of Ben Lomond. It may take up to 3 hours to climb but the views all along the way are breathtaking.
Less than an hour from Glasgow it is a great day trip from the city or as a stopping off point on the road further into the Scottish Highlands.
