Rather than take the suggestion of our guidebook (and spend 6 hours floating on the Bosporus only to navigate our way back to the dock of origin with a little trickery), we headed to the west of the Galata docks in Eminonu and bought a ticket for an afternoon ferry on one of the hourly departures on the Turyol line. The boat rides that the company offers are just 1.5 hours in duration and perfect for a picnic if you time it right, so we picked up a couple of pide from the stands near the docks, and hopped aboard with a handful of other tourists and locals for the most scenic lunch we had on our two-week trip.
The boat sailed up the Bosporus, and we took in the diversity of architecture along the shore, as we knew we would. But what we didn't anticipate enjoying so much was the people-watching aboard the boat. Because we weren't on a commuter ferry, or a tourist attraction, we got a chance to bump elbows with local folks who love the Bosporus and were just out for a little fresh air and some time to chat, have lunch, get away; I can't imagine having enjoyed a bit of time on the Bosporus more!
