The souterrains of mainland Scotland are found mainly in the eastern lowlands, with many in the fertile agricultural lands of Perthshire and Angus.
Raitt’s souterrain is further north, situated on a hillside above the wide flood plain of the River Spey, with views across to the Cairngorms.
It is shaped like a horse shoe, with a short narrow passage at the entrance which leads to a much roomier tunnel with plenty of headroom. The rear of it is stump-shaped, rather than ending in a circular chamber, as many do.
After it was discovered in 1835 it was broken into from the side, destroying a good part of the side and roof but making easy access along the remaining passage.
The souterrain is on the Kingussie Paths Network and is a short distance up the way-marked route to Raitt’s Township, a ruined settlement site.
Leaving the B9152 at Lynchat, the Raitt’s Township walk and the souterrain are both signposted.
