Indian nationals do not need a permit to visit most parts of Sikkim, but a Restricted Area Permit (RAP) is required for visiting Nathula Pass, Tsomgo Lake, and other border areas. Foreign nationals need a Protected Area Permit (PAP) to enter Sikkim, which can be obtained from Sikkim Tourism Offices or through registered tour operators.

Key attractions include Gangtok, Tsomgo Lake, Nathula Pass, Pelling, Yumthang Valley, Lachen, Lachung, Gurudongmar Lake, and the various monasteries such as Rumtek and Pemayangtse.

Sikkim offers a range of accommodation options, from luxury resorts and hotels to budget guesthouses and homestays. Major towns like Gangtok and Pelling have a good selection of hotels, while smaller villages offer charming homestays.

Sikkim is generally considered a safe destination for travelers. However, it's always advisable to take standard precautions, such as avoiding isolated areas at night, keeping an eye on personal belongings, and following local guidelines.

Pack warm clothing, especially if traveling in the winter or visiting high-altitude areas. Comfortable walking shoes, rain gear, sunscreen, and a basic first-aid kit are also recommended. Don't forget to carry any necessary permits and identification documents.

Local transportation options include taxis, shared jeeps, and private vehicles. For remote areas, hiring a local guide or driver is advisable. Public buses are available but may not be as frequent or convenient.

Respect local customs and traditions. Remove shoes before entering a monastery or someone's home. Dress modestly, especially when visiting religious sites. Avoid touching religious artifacts and always ask for permission before taking photos of people.
