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 there, you can follow an 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 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.
Nha Trang to Quy Nhon (Vietnam)
This 134-mile stretch of highway is spectacular—it's got mountain scenery on the inland side of the road and stunning sea views with golden beaches on the ocean side of the road. It is easy to stretch this road trip into a vacation to stop in the many towns and villages along the way. Plus, you'll find plenty of places to relax on a beach.
Every two years, there is a week-long festival where visitors drive the route together and take part in a large celebration. If you want a memorable experience between Nha Trang to Quy Nhon, consider joining in that celebration.
