Xinduqiao is a small, picturesque Tibetan town known as “Photographer’s Paradise.” Hidden in the mountains, it has unique, traditional Tibetan culture embedded within the stunning natural sceneries of snow-capped mountains and endless grasslands. Colorful prayer flags flutter about in the wind, against the clear blue sky and the snow mountains. You can visit local villages and experience a piece of their daily life.

Litang – Haizi Mountain and Sister Lake

Litang is known to be the “world’s highest town” at 4,014 meters (13,170 feet). Here, you will find Haizi Mountain and Sister Lake sitting quietly against each other. They form a typical picture of the Tibetan plateau, a serene and otherworldly landscape.

Changqingchun Ke’er Monastery is a Tibetan Buddhism academy that seems to be cut off from the rest of the world. The red, yellow, and white architecture sits in harmony with the pasture around it.

Daocheng – Yading Nature Reserve

Daocheng is most famous for the Yading Nature Reserve. It’s known for the most picturesque and surreal alpine landscapes. Many people travel to Sichuan just to witness its sceneries. Daocheng Yading has three sacred snow mountains and a number of high-altitude lakes like Pearl Lake and Milk Lake. They are like mirrors hidden among the tall mountains, reflecting the blue sky and the greens nearby.

Basu – 72 Turnings of Nujiang

On the side of Nujiang Mountain, the road itself becomes a breathtaking sight and experience. This 12-kilometer (7.5 miles) part of the highway makes many sharp turns across the mountain and varying altitudes. It’s amazing to see the roads meandering across the greens, but driving on it is a much more thrilling experience. It takes a lot of caution and concentration to finish this part of the journey.

Basu – Ranwu Lake & Lagu Glacier

Basu is also called the “Hometown of Glaciers.” The clear lake and vast glaciers will transport you back to ancient times. It’s as if the modern society doesn’t exist. You will see the blue lake sit amongst the green sea of grass. The snow-capped peaks are reflected within.

Nyingchi – Midui Glacier

Midui Glacier is another amazing sight to see along G318 highway. It’s the lowest glacier in the world. It’s an excellent spot for photography as the white glacier makes a perfect white canvas for the forests that take on various colors.

Nyingchi – Lulang Forest

“Lulang” in the Tibetan language means the “Dragon Valley,” where the dragon resides. It’s an ancient, pristine forest with a sea of green forests located amongst mountains and glaciers. Every spring and summer, the vast field is dotted with wildflowers. Together with wooden residential houses and flowing streams, it almost seems like a fairyland.

Nyingchi – Namcha Barwa

Namcha Barwa has bee ranked the most beautiful snow peak in China by China National Geographic. It is the highest peak in Nyingchi and the 28th in the world at 7,782 meters (25,532 feet). The top of the mountain is steep and sharp, covered in snow all year round, but at the foot of the mountain and in the valleys, there’re large areas of dense forests.

Lhasa – The Holy City of Tibetan Buddhism

And finally, the destination of your road trip, Lhasa. It’s the most popular place to visit on Tibet tours. Having been a center of Tibetan Buddhism since the 7^th century, there are many spiritual sites to visit. Potala Palace is the most iconic site that attracts countless pilgrims to witness its magnificence. It is the highest ancient palace in the world with splendid Tibetan styled architecture.

Aside from its spirituality, you will also find rich Tibetan culture in Lhasa. Barkhor Street is the best place to experience local culture, see traditional arts and crafts, taste Tibetan foods, and discover local daily life.

Best Time for a Road Trip on the G318 Highway

The best time for a road trip from Sichuan to Tibet is in Spring, April and May, and Autumn, September and October. These months are the best time to visit Tibet because the weather conditions and natural sceneries are at their peak.

In the spring months, snow is starting to melt in the areas at a lower altitude. Flowers are in bloom, adding colors to the vast meadows. You will witness some of the most amazing landscapes. Although where the altitude is higher, it’s still a little cold, overall, the journey be smooth and full of surprises.

Fall is the best time to see the snow peaks as the weather will be the clearest. The trees start to turn in color in the mountains. Yellow, red, and orange foliage appear particularly vibrant against the white snow. With less rainfall and still relatively warm temperature, it’s the perfect time for outdoor exploration.

Summer is the rainy season in the region. Rainfall can cause landslides or mudslides in the mountains, posing risks to your journey. And the heavy snow in the winter will also make driving more difficult.
