Why it's Wildland
8.2Glen Roy’s long, level ‘Parallel Roads’ are traces of ice-dammed lakes that formed and drained at the end of the last Ice Age.
This is a landscape where the evidence of ancient ice is written across the hillsides. The Parallel Roads, river terraces and landslips make the geology the reason to come, while the mountain setting and native woodland add a strong sense of place.

The experience
Come for the Parallel Roads and take time to read them in the wider landscape: look for the level terraces, river fans and landslips described by NatureScot. This is a rugged, remote Highland reserve, so plan conservatively and check access and conditions before travelling.
Things to do
Spot the Parallel Roads
Look for the conspicuous level lines across the hillsides. NatureScot explains them as former shorelines of ice-dammed lakes formed and drained at the end of the last Ice Age.
Look for other glacial landforms
Beyond the headline terraces, look for river fans, terraces and landslips in the wider valley landscape.
Watch for Highland wildlife
NatureScot says visitors may see red deer, ravens and buzzards, and occasionally a golden eagle.
Find spring flowers in the woodland
Look for pockets of native birch and oak woodland along the river and on the slopes; NatureScot notes that these are rich in spring flowers.

Verified history
At the end of the last Ice Age, ice-dammed lakes formed and drained in Glen Roy. Their former water levels left the parallel lines now visible on the hillsides. NatureScot also identifies river fans, terraces and landslips as part of the reserve’s glacial landscape. For centuries, geologists debated the origin of the lines before the ice-dammed-lake explanation resolved the puzzle.
Hidden details
The ‘roads’ are former lake shorelines — Despite their name, the Parallel Roads are geological terraces: traces of successive levels of ice-dammed lakes, not built roads.
Look beyond the famous lines — NatureScot also points to river fans and landslips among the reserve’s glacial landforms.
