Nestled between Bhutan and Nepal, tiny Sikkim - once an independent Buddhist Kingdom -became a state of India in 1975. Measuring just 40 by 70 miles (2800 square kilometers), its terrain rises from just above sea level to the icebound summits of Kanchanjanga (28.208 if), third highest peak in the world. Sikkim's flora and fauna naturally cover a wide spectrum, from tropical to alpine. Nowhere else in the world in such a small area can one find wildlife of such varieties: some 600 varieties of orchids and rhododendron in every color from red, pink and white to yellow and lavender. Forests are magically primeval and refreshingly intact, spared the chopper's axe to a relatively sparse population. The people of Sikkim are of three distinct heritages: Lepcha, believed to have originated from the border area of Assam and Burma, the Bhutia, who settled from Tibet almost 400 years ago; and the Nepalese, who Sikkimese peoples' unique cultures and natural friendliness add immeasurably to the visitor's enjoyment. Some of the highlights of Sikkim include the Tibetan buddhist tradition, and the neat and clean open air bazaars in the hillside capital Gantok. Hotels are attractive and comfortable, and local restaurants offer Tibetan. Sikkimese and Chinese food. Cultural programs are available on request.
