Zuluk is a small village in East Sikkim at around 10,100 feet, once a transit point on the trading route between India and Tibet and now known chiefly for the dramatic zigzag road that switchbacks up the mountainside just above it. Counted from certain viewpoints, the road's hairpin turns number well into the thirties, and the sight of the full loop from above — especially at sunrise with Kanchenjunga lit up in the distance — has made Zuluk one of Sikkim's most distinctive road-trip destinations. The village suits travelers who want a genuinely offbeat, homestay-based experience rather than a resort stay — Zuluk has no hotels, only local family-run homestays offering basic but warm hospitality. The main activity is simply the drive itself, extending onward to Thambi Viewpoint for the classic sunrise shot, and further to Nathang Valley and Kupup for a fuller taste of the Old Silk Route. Because the entire route runs through a protected border area, only vehicles registered in Sikkim are permitted, and travelers need a Protected Area Permit arranged in advance — most visitors book through a Zuluk-based or Gangtok-based tour operator to handle this seamlessly.
