Gangtok, Sikkim’s capital, is known for its modern amenities and planned cityscape, while Darjeeling, West Bengal, is famous for its tea gardens and old-world charm. Both are popular Himalayan hill stations, connected by a scenic 100-kilometer road trip that takes around 4 hours, passing along the Teesta River. They offer a mix of city life and mountain scenery, with Gangtok having modern facilities and Darjeeling focusing on traditional attractions like the Himalayan Mountain Railway.
