It's not allowed to bike the highway bridges/tunnel across the Bosphorus, so at Üskudar I got off the main road and rolled down to take a ferry being the nicest way to finsih this 12,000k long Silk Road journey from Xi'an in China. However, the last Yenikapi ferry was a couple of hour before at noon, and I had no decent map to ask for alternative ferry destinations. So I ended up taking the metro and train to Yenikapi and biking the last kilometres to my hostel....
