In early August while trekking in the Pirin Mountains I was taking these pictures which I later on forgot to post, so here they are. Pirin Mountains are located around 2 hours drive away from Sofia with the highest peak at 2914 meter. There are several huts in this Bulgarian mountain range but camping is also possible as always. If you camp be prepared with warm clothes as the nights are getting really cold even in the summer.
Abandoned construction sites can make a good last-minute sleeping place inside a city, for example when hitchhiking and getting stuck.
