Banca Popolare di Sondrio ATM (Varzo)
While San Domenico itself is small, an ATM from Banca Popolare di Sondrio is available in the nearby larger village of Varzo, offering cash withdrawal services for most international cards. It's advisable for visitors to carry some cash, especially when visiting smaller establishments or rifugios in higher altitudes where card payments might not always be accepted. The ATM is accessible 24/7. Visitors should plan to use this facility before heading up to San Domenico if they foresee a need for cash.
