Singalila Ridge is a prominent north–south Himalayan ridge extending from the Darjeeling hills of northwestern West Bengal into western Sikkim in northeastern India, with its western slopes descending into the Ilam District of eastern Nepal.Government of Nepal, Survey Department. "Topographic Map of Eastern Nepal." 2020. The ridge forms a natural divide between the lower ranges of the Darjeeling Himalayas and the higher Himalayan massifs to the west, and is noted for its extensive high-elevation forests, biodiversity and long-distance trekking routes.
The two highest summits of West Bengal, Sandakphu at and Phalut at , lie along the ridge and offer panoramic views of Kangchenjunga and, on clear days, distant views of Mount Everest.West Bengal Forest Department. "Singalila National Park Biodiversity and Landscape." 2021. Much of the ridge is protected within the Singalila National Park, a major conservation area known for its rhododendron forests, red panda habitat and alpine landscapes.
The ridge is a well-known trekking destination, with routes connecting Manebhanjan, Sandakphu, Phalut and the highlands of western Sikkim. Additional high-elevation passes such as the Singalila Pass link the ridge to remote border regions near Nepal and Sikkim, forming part of a larger trans-Himalayan trail network.Indian Mountaineering Foundation.

Singalila Pass Singalila Pass is a high‑elevation mountain pass located near Uttarey in western Sikkim, forming part of the northern extension of the Singalila Ridge. The pass lies close to the India–Nepal border at an elevation of about , and serves as an important link between the upper Sikkim highlands and the eastern regions of Ilam District in Nepal.Government of Sikkim, Tourism Department. "West Sikkim Trekking Routes." 2022.
The pass provides access to several trekking routes, including trails leading toward Phoktey Dara, Kalijhar, and the northern sections of the Singalila Ridge. It is known for panoramic views of the Kangchenjunga massif and surrounding Himalayan peaks during clear weather.Indian Mountaineering Foundation. "Singalila Ridge Survey Notes." 2020.
Due to its proximity to the international boundary, Singalila Pass is monitored by the Sashastra Seema Bal (SSB). The area remains largely undeveloped, with limited seasonal tourism focused on high‑elevation trekking and nature observation. Alpine forests, rhododendron belts, and remote ridgeline landscapes characterize the terrain around the pass.Sikkim Tourism. "High-Altitude Trekking in West Sikkim." 2021.
