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.

As suggested by Sikkim Tourism, the best time to visit Sikkim is either between March and May or October and mid-December. If you want to witness the blooming natural beauty in Gangtok best season to visit would be in spring, from March to May. Autumn, on the other hand, brings the clear view of Himalayan Range.

Darjeeling is a town in India's West Bengal state, in the Himalayan foothills. Once a summer resort for the British Raj elite, it remains the terminus of the narrow-gauge Darjeeling Himalayan Railway, or “Toy Train,” completed in 1881. It's famed for the distinctive black tea grown on plantations that dot its surrounding slopes. Its backdrop is Mt. Kanchenjunga, among the world’s highest peaks.

While summer months from April to June are the ideal time to travel to Darjeeling, some travellers including couples also prefer to visit the beautiful town during winter months from October to December.
