Good day. Of course, there is no railway connection in Varadero, but there is an intercity bus station. From it you can get to almost any major city in Cuba, including the capital Havana. You can also go far to the east: to the city of Santiago de Cuba. You can pay in euros and dollars. There is a bus station on 36th Street. We went from this station to Havana and Esmeralda Beach. The most beautiful in Cuba. Very far away, but it's worth it)))
