San Marino is one of the smallest country in the world. Actually is the county within the country, because it is surrounded only by Italy. San Marino is located only about five hour drive from Ljubljana so it is – with nearby Rimini – great choice for a weekend trip from Slovenia, especially in spring or autumn.
We visit San Marino four years ago, when we returned by ferry from Greece to Ancona. This was a great end of our Greece wandering.
