Sikkim: 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.
