The Mountain Tunnels of Guoliang and Xiyagou (China)
The Taihang Mountains have been a remote part of China with limited access for centuries. Even though most of the country's road system is publicly funded, it was decided that it was uneconomical to build roads in this region, so the locals ended up blasting their own roads out of the cliffs.
Driving through these tunnel roads is a remarkable experience, as they are inside the cliffs, and the windows along the route have spectacular views over the surrounding mountain scenery. These two tunnels are connected by a road that takes you through the Taihang Mountains on a relatively short stretch of 60 kilometers. Most visitors get to the area by going through the city of Xinxiang.
The Hokkaido Scenic Byway (Japan)

Golden Road to Samarkand (Uzbekistan)
Uzbekistan is a country that is well off the tourist trail for most people, but it has an interesting history (the city of Samarkand was once the capital of the large empire of Tamerlane), and it's a fascinating place to explore.
Although there isn't a formal route, most visitors will fly into the capital city Tashkent, and then transfer to Bukhara. This beautiful old city is home to many historic sights, and from here, you can follow a historic Silk Road route to Samarkand. The historic ruin of the Rabati Malik caravanserai (inn) is a wonderful place to stop along the way. After arriving in Samarkand, you can explore the history of the city by visiting a few landmarks, such as the Registan square or the Ulugbek observatory.
The Karakoram Highway (Pakistan and China)
Often hailed as the highest road in the world, this trip is as much an amazing engineering feat as it is a tourist attraction, and there are many people who travel long distances to be able to drive or ride a motorbike over the Himalayas on this road connecting China and Pakistan.
There are some stunning scenic areas with beautiful lakes and mountain views along this road that are well worth stopping to enjoy. Many people also use this route to gain access to some of the best mountain climbing spots in the world. The road rises to higher than 15,000 feet, so be conscious of the potential for altitude sickness and how it could affect you during the trip.
