Insider Driving Tips
Secure your Inner Line Permit (ILP) at least 24 hours in advance through a registered Sikkim travel agent; individual applications are rarely processed for the border.
Carry a portable oxygen cylinder and start a course of Diamox (after consulting a doctor) to mitigate Acute Mountain Sickness (AMS) as you rise to 14,140 feet.
Photography is strictly prohibited in many areas near military installations and the actual border gate; always check for signs to avoid confiscation of equipment.
Only Indian nationals are permitted to visit Nathu La; foreign tourists are restricted to Tsomgo Lake and must travel in groups of two or more.
Travel in a high-clearance 4WD vehicle like a Mahindra Scorpio or Tata Sumo, as the road conditions can deteriorate rapidly due to landslides or sudden snowfall.
