Bansko
The most complete family resort in Bulgaria, and the clear pick.
Bansko pairs the country's most modern lift system, anchored by a fast gondola, with its highest and most snow sure terrain, plus the best snowmaking in Bulgaria to back it up. The ski schools are excellent and well drilled in teaching children in English, the beginner area up at the mountain hub is gentle and well organized, and the green to blue progression carries young skiers a long way. Down in the valley, the old town gives families cobbled streets, hearty restaurants and a real Bulgarian atmosphere for the evenings.
It takes top spot because it combines the best snow, the best lifts and the best teaching in the country, then adds a characterful town below. The one catch is the morning gondola queue in peak weeks, worth beating with an early start.
