Protected Area Permits (PAP) are strictly mandatory when you are exploring the high-altitude border zones like Nathula Pass, Tsomgo Lake, Lachen, Lachung, Yumthang Valley, and Gurudongmar Lake. If you are an Indian traveler, you must carry a valid physical Voter ID, Passport, or Driving License along with 4 to 6 passport-size photographs. Do keep in mind that at the military checkpoints, the Aadhaar or PAN cards are not accepted as valid IDs. However, if you are a Foreign citizen, you are required to acquire an Inner Line Permit (ILP/RAP), alongside a PAP. Also, foreigners are permitted to explore these border zones only if they travel in groups of at least two, which is arranged via registered tour operators. However, foreign nationals are restricted to visit only Lachung and Yumthang Valley, as Gurudongmar Lake and Nathula Pass remain closed to foreigners.
You must pack multi-layered thermal innerwear, fleece mid-layers, and a heavy windproof down jacket for autumn and winter, when the high passes reach sub-zero temperatures. Also, it is a must for you to bring sturdy trekking footwear with deep rubber treads, UV sunglasses for snow glare, and high-SPF sunscreen. And in case you are traveling during the monsoon season, you must pack waterproof rainwear, sturdy umbrellas, and anti-slip walking shoes.
Getting hold of local high-ground-clearance SUVs with experienced hill drivers for rugged northern routes is the best you can have to ensure a safe road journey. Besides this, monitor every information related to NH-10, especially during peak monsoon season, from July to first week of September to maintain safety and precaution during landslides. Also, drink 3 to 4lts of water, daily, to prevent AMS (Acute Mountain Sickness) when you get over 10,000ft.
