Distance is basically the whole decision in Beykoz — by the time you reach wherever you're headed, you've crossed half the city, and the crowds simply didn't bother following. This far end of the Bosphorus trades showiness for groves, meadows, and the smell of fish along the shore. Stretch it all the way to Anadolu Kavağı, climb the hill, then remember why you bothered over a tea break. Come on a weekday — the roads are empty and so is your head. Too lazy to plan? Leave it to the dice, the greenery handles the rest.
