Ruthven

The ruins of Ruthven sit on a low mound just outside Perth, and they're genuinely worth a detour if you're staying at any of the nearby caravan parks. What remains are the foundations and lower walls of a medieval castle that once commanded views across the Tay Valley - now it's more of an atmospheric walk than a major sight, but that's rather the point. You'll find broken stonework, grass-covered banks, and enough historical weight to spend twenty minutes poking around if you're interested in how the Scots fortified their territory in the 1300s.

Historians and anyone with a taste for crumbling stone will get the most from it. Families with young kids might find it a bit underdone - there's no interpretation, no café, nowhere to shelter. Walkers heading out from Perth Caravan Park or Scone Camping will find it makes a solid short loop, especially if the weather's behaving.

Access appears to be free and unrestricted, which is generous but means there's minimal infrastructure. Allow thirty minutes to an hour depending on how much you want to linger and photograph the stonework. The walk from the nearby car area is straightforward - no scrambling involved. Best to go when it's not waterlogged; Perthshire can be wet, and this spot doesn't drain brilliantly. It's not a headline attraction, but if you're staying put for a few days at one of the caravan sites round Perth, it's worth knowing about for a quiet morning out.
