Tips for Visiting Yumen Pass
- Visit in the cooler months outside the spring sandstorm season and time your visit for early morning or late afternoon light-Yumen Pass's exposed ruins photograph best at low sun angles.
- Use Dunhuang as your logistical base and book transport or a guided tour from there; the pass is remote and easier to visit as part of an organized Silk Road itinerary rather than trying to reach it independently.
