The Batasia Loop is a spiral railway created to lower the gradient of ascent of the Darjeeling Himalayan Railway in Darjeeling district of West Bengal, India. At this point, the track spirals around over itself through a tunnel and over a hilltop. It was commissioned in 1919.

At sunrise, the peaks of Kanchenjunga are illuminated before the sun is seen at lower elevations. From Tiger Hill, Mount Everest (8848 m) is just visible. Kanchenjunga (8598 m) looks higher than Mt. Everest, as it is several miles closer than Everest. The distance in a straight line from Tiger Hill to Everest is 107 miles (172 km).

Kangchenjunga, also spelled Kanchenjunga, is the third highest mountain in the world. It rises with an elevation of 8,586 m in a section of the Himalayas called Kangchenjunga Himal delimited in the west by the Tamur River, in the north by the Lhonak Chu and Jongsang La, and in the east by the Teesta River.
