Waulkmill

The remains of Waulkmill lie scattered across farmland just outside Kinross, and unless you know what you're looking for, you might walk straight past them. This is a Roman fortlet - one of those smaller military outposts that dotted the Antonine Wall's supply chain back in the second century AD. What survives today are earthworks: a series of grass-covered banks and ditches that once formed the defensive perimeter. It's not dramatic, but it's proper absorbing if you've got even a passing interest in Roman Scotland.

You'll need a good twenty minutes to properly explore the site and get your head round the layout. Bring binoculars if you're keen to spot detail in the earthworks from different angles. The ground can get boggy after rain, so decent boots aren't a luxury. It's free to visit and open year-round - there's no gatehouse or visitor centre, just the landscape itself.

History enthusiasts will find this worth the detour; families with young children might lose interest quickly unless they're already Roman-mad. The real appeal is in connecting the dots with other sites along the Antonine Wall itself, scattered across Perthshire and Fife. If you're based at Gallowhill Caravan & Camping Park just down the road, you could combine this with Rough Castle or other wall fragments in the region to make a proper archaeological day of it. On its own, though, it's a quiet spot for contemplative wandering rather than a crowd-puller.
