Drum

Drum is a mountain summit in the Carneddau range of northern Wales, rising to 770 meters with grassy slopes covering its lower sections. A distinctive cairn marks the peak and is visible from several walking routes in the area.

The mountain served as a testing ground in 1956 for Blue Joker, an experimental airborne radar system developed for military purposes. This use demonstrates the site's strategic importance during the Cold War era.

The Welsh name 'Y Drum' describes a ridge formation, reflecting how locals perceive the mountain's shape in the landscape. This naming tradition is still used by people in nearby communities when discussing the Carneddau hills.

Visitors can reach the summit via several marked trails starting from the village of Rowen in the surrounding area. The path is best walked during dry weather, as the grassy slopes become slippery after rain.

Water flowing from the eastern section of the mountain channels through the Afon Tafolog stream, which eventually joins the larger River Conwy. Following this watercourse reveals how the peak functions as a water source for the surrounding landscape.
