The Den o’ Alyth is a scenic woodland where the Alyth Burn has carved dramatic cliffs of Old Red Sandstone - a rock formed 400 million years ago that was later shaped by glacial forces and erosion. The landscape, marked by steep slopes and boulder-strewn beds, reflects a powerful geological past.
The dynamic stream supports a diverse ecosystem. Wildlife such as dippers, grey herons, tree creepers, woodpeckers, great tits, grey wagtails, and red squirrels thrive in this ever-changing environment, while roe deer sometimes appear along the water's edge. In winter, a rare phenomenon called hair ice can form on decaying wood when specific fungal activity triggers thin strands of ice to emerge.
Historically, the Den was part of the ancient Forest of Alyth, a royal hunting reserve dating back to the 12th century, even frequented by King Robert I. Today, careful woodland management continues to balance native and non-native species, ensuring the preservation of this natural and cultural heritage.
