- Darjeeling and Sikkim offer some of the finest trekking experience in the Himalaya. The region’s vast unspoiled mountain ranges are a trekker’s delight and its amazing range of flora and fauna a naturalist’s dream. The region abounds in rhododendrons, magnolias, primulas, orchids and ferns of numerous varieties. About six hundred different species of birds inhabit the emerald green forests on the slopes of the mountains. This trek is perhaps one of the best and certainly the most popular of all the treks in Darjeeling for those having a limited time at their disposal. It offers the travelers an excellent view of the Kanchenjunga and the Everest group of mountain peaks in Nepal, Sikkim and Bhutan.
