Complete Guide to Sichuan–Tibet Highway Northern Route (G317)

The Sichuan–Tibet Highway Northern Route (G317) is one of the most remote and culturally immersive overland routes connecting Chengdu with Lhasa. Compared with the more popular southern route G318, G317 passes through deeper Tibetan regions, higher plateaus, and less-traveled landscapes, making it ideal for experienced travelers seeking an authentic overland journey.

As a Chengdu-based travel agency specializing in western China and Tibet overland journeys since 2007, WindhorseTour has organized and supported multiple expeditions along the G317 route, working directly with local Tibetan guides and logistics teams across Sichuan, Kham, and eastern Tibet.

What Is the Sichuan–Tibet Northern Route (G317)?

The G317 is the northern branch of the historic Sichuan–Tibet Highway, running from Chengdu through western Sichuan and eastern Tibet before reaching Lhasa. This route travels across vast high-altitude grasslands, deeply Tibetan regions, and some of the least-visited counties in Kham and eastern Tibet, offering a more rugged and culturally immersive experience than the southern route.

Alternative Route Due to Sertar (Larung Gar) Access Restrictions

Due to the long-term closure of Sertar (Larung Gar Buddhist Academy) to foreign travelers, we recommend an alternative approach that diverges from the official G317 route earlier in the journey.

Instead of heading north through Ma’erkang and Sertar, travelers proceed northwest from Chengdu via Mount Siguniang, Danba, Bamei, Daofu, and Luhuo before reaching Garze, where the journey rejoins the main Sichuan–Tibet Highway Northern Route (G317).

This alternative route offers richer alpine scenery, deeper cultural immersion, and more developed tourism infrastructure, including a wider selection of hotels and dining options, making it a more comfortable and rewarding option for international travelers while preserving the spirit of the G317 overland journey.

Is the G317 Northern Route Fully Paved?

Yes. The Sichuan–Tibet Highway Northern Route (G317) is now predominantly paved and significantly improved compared to earlier years. Most sections are asphalted and suitable for regular vehicles, though roadworks, weather-related damage, and temporary gravel sections may still occur, especially near high mountain passes and remote areas.

---

Best Time to Travel the Sichuan–Tibet Northern Route

The best time to travel the G317 route is May–June and September–October, when weather conditions are relatively stable and mountain passes are generally accessible. July and August can bring heavy rainfall and occasional landslides, while winter months are not recommended due to snow, ice, and high-altitude road closures.

The G317 route involves sustained high-altitude travel, with several passes exceeding 4,500 meters. Travelers should allow sufficient time for gradual acclimatization, avoid rapid ascents, and plan rest days when necessary. Proper pacing is essential to reduce the risk of altitude sickness and ensure a safe and comfortable journey.

What Vehicle Is Best for the G317 Route?

Although the G317 Northern Route is mostly paved, a reliable high-clearance SUV or 4WD vehicle is strongly recommended. These vehicles provide better stability on rough sections, greater comfort on long driving days, and increased safety when encountering sudden weather changes, roadworks, or unpaved detours, particularly during shoulder seasons.

Why vehicle choice matters on G317

The G317 is a spectacular but demanding high-altitude road, with sharp mountain curves, occasional gravel stretches, and rapidly changing weather conditions. Landslides or snow can temporarily affect certain passes, particularly in spring and during the monsoon season. Traveling with an experienced local driver familiar with Tibetan terrain helps ensure safety and smoother day-to-day logistics.

Permits Required for the Sichuan–Tibet Highway

Foreign travelers entering Tibet via the G317 route requires a Tibet Travel Permit, arranged through a registered local travel agency before your trip. This document is checked at multiple points beyond Dege, so ensure it’s ready and accessible. Foreign travelers must join an organized tour or private guided arrangement to continue beyond the Sichuan border into Tibet.
