Lagg Bridge (C147)
Skirting the southern edge of the Isle of Arran, this long, flowing tertiary road mixes dual-track width with sweeping coastal vistas. It provides a more relaxed, easygoing drive than the Highland single-tracks, allowing you to enjoy the views towards Ailsa Craig without fighting the steering wheel.
The road surface improves noticeably past Kildonan, letting you settle into a comfortable cruising rhythm.
