Climb to an Iron Age hillfort with views over Strathtay

This part of Scotland was long occupied by the Picts, the Celtic tribe who built the prehistoric fort of Caisteal Dubh (The Black Castle). Climbing through juniper trees to the remains of the fort, unrivalled views over the River Tay open up, making clear why this was such an important defensive position.

More information

When the local Picts lived here, the stone ramparts of the fort didn't just keep out invaders, they kept out the other locals – wolves and...possibly bears.

Stone cairns stand guard a little below the fort. Some were built in the 1800s but no one knows why they're here. Do you have a theory?
