You need a weekend where you actually put the phone down. Ertuğrul Gazi Parkı Ve Sosyal Tesisleri over in Bağcılar is a way to get close to that. Outdoor spots get more crowded than expected on weekends — head out early, come back before the afternoon crowd hits. Bring water, comfortable shoes, and a spare shirt: that's the base kit, add the rest depending on the season.
