Experience the legendary Old Silk Route through the cloud-covered loops of East Sikkim. This 4-day circuit takes you from the tropical forests of Siliguri to the snow-clad passes of Nathang Valley and the iconic 32-hairpin bends of Zuluk. Please note: Private vehicles, including motorcycles, are not permitted on the Old Silk Route/Zuluk; riders must arrange for Sikkim-registered vehicles for this section. Sikkim is in the process of transitioning to a digital permit system for protected areas, with discussions ongoing as of August 18, 2026, regarding an operator-routed system. Foreign nationals are currently not permitted to visit Zuluk and the Old Silk Route; they are only allowed to visit Tsomgo Lake (East Sikkim) and Yumthang Valley/Zero Point (North Sikkim) with online permits. Recent continuous snowfall in March has blanketed roads in high-altitude areas like Tsomgo Lake and Nathang Valley, requiring extra caution. A recent landslide in the Nathula region on September 10, 2026, due to heavy rainfall, has blocked several roads, requiring extra caution for routes in this area. Additionally, Nathula Pass is regularly closed on Mondays and Tuesdays. National Highway 10, connecting Sikkim with West Bengal, is currently undergoing night-time traffic restrictions between Sevoke Coronation Bridge and Rangpo from 9 PM to 6 AM, for slope protection and landslide-prevention work. These restrictions are in effect from October 7-15 and October 26-November 5, 2026. During these periods, all vehicles are stopped overnight. Additionally, the Centre has approved a significant upgrade for the Rangpo-Ranipool stretch of NH-10, which will involve ongoing construction of tunnels, viaducts, and landslide treatment, potentially causing further delays. A test of endurance rewarding riders with Kanchenjunga views and high-altitude adventure.
