A winded road drops out of Carrick and the valley opens like a map of old ice—green slopes framing a single ribbon of tarmac that invites you to ride. On a rented high‑quality e‑bike you’ll pedal out of the village, shoulders easing as the motor assists the first climb, then push off for a fast, exhilarating descent into Granny Valley. The sound of water grows louder: Assarancagh Waterfall daring you to stop. At the valley floor Maghera Beach waits with broad white sand, followed by the sheltered Loughros Beg Bay that edges toward Ardara.
