evidence: The gem of the Slovene Riviera and one of the most beautiful places in the entire country, Piran is a historic harbour town set on a narrow peninsula, hemmed in by the Gulf of Trieste on three sides. [...] When to go: Piran is a coastal town with a defined ‘on’ and ‘off’ season. Summer is by far the busiest time of year, when prices are highest and crowds are thick. Winter, by contrast, sees the population shrink and many (but not all) restaurants, cafes and hotels close. Spring (May/June and September/October) are a nice compromise. [...] Peninsular Piran is comprised of dozens of narrow stone passageways, cobbled alleys and pitched streets interspersed with small market squares, fountains and sculptures.
