Best beaches near Istanbul accessible by public transport

Heybeliada has a beach near the Cevahir aquapark — the water is cool but not crowded and generally decent. Accessible by ferry to the island.

The rocky-area beach near Florya is public: locals arrive in the evenings and sometimes leave litter and bottles. No sun loungers are provided or planned there, as it is a public beach.

Noya Beach on Kınalıada (the nearest Prince's Island) costs 1000 TL entry, no outside food or drinks allowed. The beach is terraced with a pool and is usually uncrowded. It closes at 18:00. Access is by ferry/water taxi transfer.

Florya private beach is kept clean with staff regularly tidying the water. Downsides: the toilets are very far from the beach, and bottled water isn't freely available near the main beach area — you have to ask at the bar. A self-serve fridge with water exists only in the 16+ zone. The public toilet opposite Palm Beach on the promenade is decent.
