A park by the sea. Fresh air and a promenade. Playgrounds, picnic tables. Small cafes. There is a beach nearby. Bike paths. It's nice to take a walk before going to bed.
The park is large, green, clean, and there are "restrooms" on the territory. You can enter them through the turnstile by attaching an Istanbul travel card. There are playgrounds! The lawns are well-groomed -mowed. People bring bedding, tables, arrange picnics, relax. The park is located on the shore of the Marmara Sea, from it you can admire the ships on the raid, there are countless of them! The beach is open in summer. There were no photos of the park itself, but there is a small video.
