Yes, ATMs are readily available in Gangtok, especially in the main areas of the city such as M.G. Marg. You will find ATMs operated by various major banks in India, including State Bank of India, HDFC Bank, ICICI Bank, and Axis Bank, among others. These ATMs typically accept both domestic and international cards.
However, when traveling outside of central Gangtok or visiting more remote areas in Sikkim, ATM availability may become sparse. Therefore, it’s advisable to carry sufficient cash when heading out of the city or planning to visit less urbanized areas. Also, given the occasional issues with network connectivity in the region, it’s a good practice to withdraw cash in advance and not rely solely on ATMs for immediate cash needs.
