I was quite confident that hitchhiking from Timișoara to Belgrade would not be that hard. The road was less than 3 hours long and I was hitchhiking into a capital. But I took my precautions anyway and tried to leave my Couchsurfer's apartment before noon.
Because of various reasons, I decided not to go to Bucharest after Sibiu. A lot of people on the way we're not very enthusiastic about the city, and I want to go back to Romania in the future anyway. I also needed to save some time because I had booked a flight from Istanbul to Tel Aviv. So I prepared myself to make my way to Serbia and I hitchhiked to Timișoara to spend my two last nights in Romania there.
From Brasov I hitchhiked the same road to Sibiu again, but not before making a stop in Codlea. I have a few friends from Berlin that are originally from that small town and I wanted to surprise them. There wasn't much to do there, so I just took a picture to proof that I had passed through the town.
We got up early in the morning, we shared breakfast and started hiking again. Voytek and Christian decided to go swimming in the frozen lake a bit down, while I wanted to go to the top. So we said our goodbyes and split up.
After visiting some cities I thought about hiking the highest mountain of Romania: the Moldoveanu in the Făgăraș mountain range. At 2544 meter, it was a bit lower than the Triglav in Slovenia.
In Turda they turned a used salt mine into a spectacular tourist attraction. The mines were first mentioned in the Middle Ages and salt was being mined until 1932. The mines are now used for halotherapy, an alternative treatment for asthma, and as a tourist attraction.
A rainy evening in Cluj-Napoca:
The second day of hiking, I went to one of the top sights of Maramureș: the old wooden churches.
