Early full-day excursion to Changu/Tsomgo Lake and Nathula Pass; special permits arranged via hotel/agent are mandatory and Nathula is weather- and security-dependent.
Visit the high-altitude pass at the India-China border — requires permits and may be closed on short notice, so confirm with your agent/hotel the day before.
Drive approximately 4–6 hours depending on route (via Pakyong/Rongli/Rorathang or Nathula-side roads); the climb brings you to the historic Old Silk Route with famous hairpin loops.
Check into a homestay or simple lodge near Zuluk/Kupup, then visit the famous snake-like hairpin loops and viewpoints — ideal for late-afternoon light.
