Protected Area Permits And Restricted Area Permits

This is especially if you are planning on visiting places like Lachen, Lachung, the Yumthang Valley, and the Gurudongmar Lake.

What is more, foreign nationals need to procure a Restricted Area Permit (RAP) if they want to access any of the areas mentioned above.
What Documents Do You Require?
You also need to carry certain documents for this trip. You must carry your passport photos, government-issued photo IDs, and the printed copies of your permit applications. You can obtain the permit via the official website of the Sikkim Tourism Department. In addition to this, you can also procure your permits at the registered Sikkim Tourism Development Corporation (STDC) travel agencies, which are typically in Gangtok.
