A beautiful place to visit, surrounded by a fortress is a nature reserve. You can drive in your own car. There is a coffee shop at the entrance, and several gazebos with outdoor tables overlooking the fortress and nature.
The facility itself offers a breathtaking view of the city.
There are few tourists, peace and quiet, a great place for a relaxing walk in the fresh air.
There are free transfers at the foot of the fortress, they take you to the fortress and back. The staff themselves are polite and ready to help.
It's still free
parking is a problem only on Sundays
You can see part of Istanbul outdoors from the terrace section, but the places you see are not the famous districts of Istanbul that you know
