San Marino is the world's oldest sovereign state on the slopes of Mount Titano, with the Three Towers crowning the limestone ridge above the Apennines, surrounded entirely by Italy.
Three Towers walking pleasant, the Crossbow Tournament between San Marino and Italian neighbours, and the Mount Titano viewpoints at peak haze-free clarity.
San Marino hits 32°C and the Apennine ridge breezier than the Riviera below, with summer concert season at the Cava dei Balestrieri amphitheatre.
Medieval Days in late July aside, autumn brings clear weather for the Three Towers loop and the Sammarinese Republic Day celebrations on September 3.
Cool winters with snow possible at Titano's peak, the Christmas market in Piazza della Libertà running through January, and the country's stamp-collecting heritage on display.
