Sozopol - Istanbul
Goal: 7 days, with stops in Tsarevo, Malko Tarnovo, Kirklareli, Hamitabat, Saray and Silivri.
Warnings: Just before Silivri, on the hills near Beyciler and Büzükkilcli there is a huge landfill with *lots* of trucks driving and crossing. Try to avoid this area! Also, don't stay in Saray, Hotel Elit is very dirty and offers quite particular services to those who are inclined.
Our goal was the Metrobüs station in Beylikdüzü, from where we took the bus to central Istanbul. It takes about 50 minutes and outside rush hours, you are allowed to take bikes on the bus. Just before entering Büzükcekmece, there is a second bridge just a little north of the main bridge - Bikemaps doesn't know it though.
