Tarabya is the bay where the Greeks summered when Pera was their winter — Therapia, healing place, on the upper European Bosphorus where the strait widens toward the Black Sea exit. The Greek summer villas have mostly gone; the embassies that took over the hill in the late 19th century are still here, behind ironwork gates and seven generations of plane trees.
Three kilometres south along the sahil to Yeniköy, past the German, French, Italian and Spanish summer residences and the wooden yalı row the European Bosphorus is famous for. Tarabya marina is the starting bay; walk south along the seafront. The embassy compounds are private but the gates and stone walls are the show.
The closer is Sait Halim Paşa Yalısı at Yeniköy — the 19th-c wooden mansion of the Ottoman grand vizier who was assassinated in Rome in 1921. Restored as a venue in the 2000s; lobby and grounds usually open to walkers. The ferry from Yeniköy İskelesi runs south to Eminönü — a slow, quiet upper-Bosphorus crossing if you want the long way home.
