There are still very few car rental companies and due to poor road conditions, insane traffic, and few parking options, it’s best just to hire a private car and driver. The coastal road linking Danang and Hoi An is manageable and takes about 40 minutes to drive 28 km (17½ miles) and should cost no more than 500,000d by taxi. From Hoi An to Hue the most direct route takes you through the Hai Van tunnel; the 140-km (87-mile) journey takes 2½ hours and costs around 1,200,000d by private car. An alternative and more scenic route takes you along coastal roads and over the Hai Van Pass, with a few stops to enjoy the view. This 160-km (99-mile) mountainous drive takes upward of four hours and costs 1,700,000d. The 227-km (141-mile) route from Hue to Phong Nha offers spectacular scenery and, outside of rush hour, the journey can be done in just over four hours, although during the rainy season, already poor road conditions around the national park area are prone to flooding and mudslides, which can add a good hour onto the journey time. A private car and driver starts at 2,000,000d.
