Valley vs. Glen: What's the Difference?

By Harlon Moss || Updated on May 20, 2024
A valley is a broad, elongated depression between hills or mountains, often with a river running through it, while a glen is a narrow, secluded valley, typically found in Scotland or Ireland

Key Differences

A valley is a large, elongated lowland area situated between hills or mountains, often formed by erosion from a river or glacial activity. Valleys can be wide and expansive, accommodating towns, farmland, and various ecosystems. A glen, on the other hand, is a specific type of valley that is usually narrower and more secluded. It is commonly found in Scotland and Ireland, characterized by its picturesque and often rugged terrain.
While both valleys and glens are formed through similar geological processes, their scale and geographical connotations differ. Valleys are broader and can be found worldwide, whereas glens are more specific to the landscapes of Scotland and Ireland and are generally narrower.
