Pick up in Hue. Drive by bus 12km out of Hue to the coast. Begin riding off the beaten track for 40km along a picturesque, narrow peninsular road from Thuan An Beach to Vinh Loc. Hop on a local ferry to cross the estuary of the Perfume River before joining Highway. From here, transfer or cycle the first of the day’s three hill climbs. After the first two (moderate) climbs of 2-3km each, cruise down to balmy Lang Co Beach for a rest/swim and lunch before tackling the final hill of the day – the Hai Van Pass, or ‘Pass of Ocean Clouds’. With a new tunnel through the mountain diverting highway traffic, the 11km of this leg will be natural and quiet. The gradient is moderately challenging and the views breathtaking!
