Sma' Glen Signal Station

You'll find yourself on a hillside above Crieff, standing where Roman soldiers once kept watch. Sma' Glen Signal Station is the remains of a watchtower from around 80 AD - not much to look at now, but the location tells the whole story. It's a low mound with some stone foundations if you know where to squint, part of a chain of signal stations that ran through Perthshire to keep tabs on the Highlands.

What you're actually doing here is walking to a viewpoint with serious historical weight. The views across the glen are what make it worthwhile - you can see why the Romans chose this spot. It's a straightforward hillside walk from the nearby road, nothing strenuous, maybe twenty minutes up and back if you're pottering about taking photos.

History enthusiasts will get the most from this one. Families with younger kids might find the remains themselves a bit underwhelming - there's no interpretation board or marked-up site that I could find, so you need a bit of archaeological imagination. Walkers heading through Perthshire will appreciate it as a proper detour with a purpose, especially if you're combining it with a broader tour of Roman Scotland.

It's free and accessible year-round, though the ground can be boggy after rain. If you're staying at Braidhaugh Holiday Lodge just outside Crieff, this is an easy morning trip that adds genuine character to your park holiday. Worth an hour of your time, less for the remains themselves and more for standing where empire-builders once stood.
