Excellent road that runs parrallel to the road.
Ride from llantwit major to Ogmore direction for the best route - look to the left for coastal views. Stop in southerdown in the top car park for a spectacular view or ride downt he steep road to the beach and Dunraven park. If your not stopping continue along to ogmaore by-sea for more spectacular sea views.
Follow the road around and back on to the A48 for a fast blast back towards Cowbridge and Cardiff - just watch out for police on Sunny Sundays!
