Lindsay Tower - Crawford Castle (remains of)

The ruins of Crawford Castle sit quietly on the edge of Biggar, commanding views across the South Lanarkshire countryside that feel properly remote despite being minutes from town. What remains is Lindsay Tower - a sturdy rectangular keep that's managed to survive centuries of Scottish weather and indifference. You're looking at serious medieval stonework here, the sort that takes a moment to properly register as you walk up to it.

It's the kind of place that appeals most to castle enthusiasts and walkers rather than families expecting a day out. There's no visitor centre, no cafe, no interpretation boards explaining what you're standing in front of - just the tower itself and the surrounding fields. That's either refreshing or frustrating depending on your mood. The walk takes twenty minutes at most, which means it works well as a quick stop while exploring the wider Lanarkshire area rather than a destination in itself.

If you're staying at Mount View Caravan Park nearby, this is genuinely worth the short drive. The tower rewards closer inspection - the stonework is impressive once you're up against it, and the views back towards Biggar are worth a photo. Go on a clear day though. Misty weather here just turns it into a vague shape in the distance. Admission appears free, though the site isn't formally managed as a tourist attraction, so there's no guarantee of access at all hours. Worth checking locally before you visit.
