Lakatnik is near the Iskar river, in the Balkan Mountains, and is easy to reach by train. It offers stunning views and steep slopes. Enjoy it when it gets too hot and dirty in the city.
Zheleznitsa is closer to Sofia, and you can go there by bus. It’s a well known destination for Sofia citizens, but during working days it’s not too crowded and very pleasant and quite place to go and recharge your batteries.
Yeah, it’s a long entry, thank you for your patience!
