North Sikkim is a restricted district — all visitors need an Inner Line Permit (Indians) or Restricted Area Permit (foreigners) to enter. This guide covers everything: the ILP, the RAP, and the additional sector permits for Gurudongmar, Yumthang and Zero Point.
North Sikkim district — home to Gurudongmar Lake, Yumthang Valley, Zero Point and the Lachen–Lachung circuit — is a Restricted Area due to its borders with China and Nepal. All Indian nationals need an Inner Line Permit (ILP) to enter. Foreign nationals require the stricter Restricted Area Permit (RAP).
The North Sikkim ILP covers access to Mangan, Chungthang, Lachen and Lachung. Specific high-altitude destinations — Gurudongmar Lake, Yumthang Valley, Zero Point — need additional sector permits obtained simultaneously from your operator.
North Sikkim permits are not available over the counter. Submit all documents 3–4 days before your departure date.
Tell your operator every place you want to visit — Gurudongmar, Yumthang, Zero Point. Sector permits must be applied for simultaneously; they cannot be added later.
Your operator will have the permit ready on your travel day. Carry originals at all checkpoints from Mangan onward.
