The Catalarik Road is the road to Uzumlu. Cross-over the D400 heading for Uzumlu, go through Catalarik on the Turgut Ozal Cad. past the big school on your left, and you'll see the big wood storage yard on the right. The fire helicopter is often parked there. Immediately after that, on your left is the entrance to the shelter just before the entrance to a large new building. If you come to the Omer Ozyer Lisesi on your right, you've missed the entrance by a couple of hundred metres.
