Home to some of Britain’s tallest trees, Reelig Glen boasts a grove of Douglas firs soaring over 65 meters (213 feet) high. The most famous among them,”Dùghall Mòr” (Gaelic for “Big Douglas”), was once crowned the tallest tree in Britai. These majestic giants thrive in the glen’s sheltered environment, creating a cathedral-like canopy that will take your breath away.
