Natural areas in Ataşehir split into easy outings and serious hikes. T.C. ATAŞEHİR BELEDİYESİ ERGUVAN BARIŞ PARKI sits on the easy side — a half-day escape you can bring kids or grandparents along for, no professional gear required. For trekking, camping, or a real mountain climb, you'll want to look for somewhere more demanding.
