Sikkim is a state in East India in the Himalayan foot hills also bordering China (Tibet), Nepal and Bhutan.The name has been coined from the words 'Su','Him'i.e. beautiful home.Though it should be better named by abode of nature.The snow covered mountains & lush green valleys not only invigorates one's soul,it also leaves the spectators bewildered by the extravaganza of its natural beauty. Nearly 40% of the total area is forested.
The state official language of Sikkim is Nepali, which is also the primary language of most locals. Many other languages such as Dzongkha and Tibetan are also spoken by smaller numbers. However, Hindi is also widely spoken as a second language, and all educated people are able to speak English.
There are no airports or railway stations in Sikkim. The only way to enter Sikkim from rest of India is by road using bus or jeep from West Bengal.
As of March 2012, it is still necessary to obtain a Restricted Area Permit (also known as Inner Line Permit) for foreigners to travel in Sikkim. The permit is a piece of paper containing your passport data and dates you are permitted to travel (typically, 15 days). When entering and exiting Sikkim, your passport will be stamped much in the same manner as when crossing state borders. Obtaining a permit is a pure bureaucratic formality and usually takes a few minutes. You will need to fill in an application form and provide a few passport photos (1 and 2 have been reported).
The permit can be obtained when crossing the Sikkim state border by road in Rangpo or Meili. It is also available from Sikkim travel desk in Darjeeling located inside the Old Bellevue Hotel (opposite to Glenary's restaurant in Chowrasta district), and from Sikkim Tourism Center in Siliguri located at the S.N.T. bus stand (the place from which government buses depart for Sikkim, S.N.T. means "Sikkim Nationalized Transport") in the vicinity of Siliguri Junction railway station (different from New Jalpaiguri station, and can be reached from there by taxi/public shared taxi), the area is known as Pradhan Nagar. The web-site of Ministry of Home affairs states that permits can also be obtained at large international airports (Delhi, Mumbai, Chennai, Kolkata), but locating the relevant facilities proved difficult due to incompetence of the personnel. Permits can also be applied for at the time of Indian visa application, or at 14 Panchsheel Marg, New Delhi 110021 (011 26115346) and 4/1 Middleton Street, Kolkata 700071 (033 22817905)
Nearest airport for Sikkim is Bagdogra, near Siliguri in North Bengal, which is 124 km and approximately four hours drive from Gangtok. Indian Airlines, Jet Airways, SpiceJet, Go Air etc. service Bagdogra linking it with other major airport in India (including Guwahati). Druk Air flys twice weekly from Bangkok, stopping in Bagdogra before continuing to Paro in Bhutan. You can also take a helicopter from Bagdogra to Gangtok.
Construction of a 50-km rail link from Sevoke, West Bengal to Rangpo, Sikkim started in 2009, but is not expected to be ready until 2015, and it'll take another few years until it reaches another 40 km to Gangtok.
Meanwhile, the nearest railway stations are Siliguri and New Jalpaiguri. Both of these have a number of trains connecting them to Kolkata. You should be able to get pre-paid taxis to Gangtok outside the railway stations easily.
The Sikkim government has fixed rate (and fixed schedule) buses plying between Siliguri and Gangtok.
Most travel in Sikkim is done by bus or jeep on road. Trekking is also a popular option. It is better to contact a travel agent in NJP or Siliguri who will provide food,lodging,travelling,permits. But beware of the touts roaming in the station or bus stand. They will lead you to a travel agent and will obtain a commission of 15% of your whole travel package.As a result your package rate will be increased. Instead after reaching NJP or Siliguri, try to contact a travel agent by yourself. Many agencies are there and the hospitality is quite the same. Dont forget to bargain. The travel agent at first demands very high price.If you are not satisfied with his package, don´t hesitate to step out and look for another agent. An economic package including Lachen,Lachung,Yamthang,Nathula,Baba Mandir,Changu lake,gangtok local site seeing will cost around 5000 rupees
