Save this one for your next Dote day

Climb the long flights of steps up Dumbarton Rock, an old volcanic plug where the Leven meets the Clyde, to the batteries and the summit of White Tower Crag.

Why it's a good date: There's been a stronghold on this rock for well over a thousand years, and the view from the top runs from the Clyde to Ben Lomond. Book ahead, and save your legs for all those steps.
