Bahceşehir Yürüyüş ve Bisiklet Yolu (Batı Başlangıç) is a natural spot in Başakşehir worth using to get some distance from the city. Nature spots aren't hard to find, but whether the trip is worth the effort is a different question — this one holds up consistently on that distance-to-payoff ratio. If you can spare half a day, you've already won.
