The island's best drive, running north from Cua Can through Ong Lang and Vung Bau to Bai Dai, then out to the cape at Ganh Dau. Roughly 40 km of coast road with beaches and fishing bays to stop at on the way. Rentals are easy to find in Duong Dong; an international permit and a helmet are the two things worth sorting before you set off.
With a motorbike, you can ride to Bai Sau (Sao Beach), visit the ancient fishing village of Ham Ninh try fresh crab or walrus meat, and visit the Dinh Cau shrine and experience beautiful sunsets, among others.
