Sikkim is a state in northeast India, bordered by Bhutan, Tibet and Nepal. Part of the Himalayas, the area has a dramatic landscape that includes India's highest mountain, 8,586m Kangchenjunga. Sikkim is also home to glaciers, alpine meadows and thousands of varieties of wildflowers. Steep paths lead to hilltop Buddhist monasteries such as Pemayangtse, which dates to the early 1700s. Hassle-free and warm-hearted, it's a state that's all too easy to fall in love with, explaining perhaps why permit regulations prevent foreigners staying too long or going too far. Clean, green and 'all organic' since 2016, Sikkim is mostly a maze of plunging, super-steep valleys thick with lush subtropical woodlands and rhododendron groves, rising in the north to the spectacular white-top peaks of the eastern Himalaya. When clouds clear, an ever-thrilling experience from many a ridgetop perch is spotting the world's third-highest mountain, Khangchendzonga (8598m), on the northwestern dawn horizon.
