Sofia and Plovdiv pair Bulgaria's two largest cities, with Sofia's Alexander Nevsky Cathedral dome and Vitosha mountain visible from the centre, and Plovdiv's Roman amphitheatre still hosting summer concerts.
Vitosha hiking accessible, Sofia parks blooming, and Plovdiv's Old Town walking comfortable before summer heat. Kapana creative district at peak terrace activity.
Hits 32°C, Plovdiv Roman Amphitheatre evening concert season at peak, and Vitosha 30 minutes from Sofia stays 8°C cooler at altitude.
Plovdiv Wine Festival in late September, Vitosha's autumn beech forests at peak colour, and Sofia's outdoor cafés along Vitosha Boulevard pleasant before winter chill.
Vitosha ski runs December-March 30 minutes from downtown Sofia, Plovdiv's Roman ruins atmospheric in winter, and Sofia Christmas market in Battenberg Square.
