Greenland Reservoir No 1

The water here is surprisingly serene given how close it sits to Glasgow's sprawl. Greenland Reservoir No 1 is a working water supply - functional rather than flashy - but that's precisely why it works as a walking destination. The path around it offers decent views across the Stirling area, and on a clear day you get a proper sense of the Scottish Lowlands rolling away from you.

It's not a destination that'll hold your attention for hours. You're looking at a straightforward walk, maybe 45 minutes to an hour depending on your pace, with the reservoir itself doing most of the scenic heavy lifting. Families with younger kids might find it a touch dull after the first loop, but if you're after a gentle leg-stretch between longer activities, it serves its purpose well.

The real advantage is proximity to the Loch Lomond parks clustered nearby - places like Loch Lomond Retreat sit just five miles away. This makes it a natural add-on if you're based at one of those sites and want a quieter morning walk without heading all the way to the loch itself. You won't need to book or pay anything to walk here, though facilities are minimal. Go early or late afternoon when the light's better and fewer people are about. It's the sort of spot that rewards a bit of effort to find, rather than a headline attraction, but that's often when Scotland shows you its best side.
