This tiny republic of 30,000 people sits in Italy’s Apennine mountains, making much of the nation a lookout to surrounding hills and valley towns. Ride a gondola from one city to the next, or pop into a concert at the Istituto Musicale Sammarinese. Hike to the famous three towers on Monte Titano, then hit a bakery for its chocolate and wafer namesake, the torta tre monti. Feel free to ditch the map and wander through sunny piazzas and crooked medieval alleys. It’s tough to get lost in a nation that’s 24 square miles. We’ll tell you how to get there, where you can sleep in a castle, and why moving here can extend your life.
