The Eminonu pier is the central commercial and transport hub of Istanbul's most historic area. It's a gateway to Sultanahmet area with so many attractions starting from the Spice bazaar in front of it, further up to Kapali carsii and then to iconic Istanbul's sites like Topkapi and Hagia Sophia. The place is always packed with both locals and tourists. Many ferry routes start from here and I suggest taking any of them, specially for Kadikoy or Uskudar as the journey to the Asian side is so impressive and beautiful. If a fish lover do try their street sandwiches sold there on many stalls, as well corn and chestnut.
The Bosphorus is one of he world's best-known waterways. We took a cruise on the Bosphorus from Eminonu Pier, it was well worthwhile. Eminonu Pier is crowded with travelers when the ferries are running; anglers always seem to be dangling their lines hopefully in the water -- someone must catch something sometime.
Nice view across to the Galata Tower. Place to get ferries - note that you might have to wander about a bit to find the right terminal, Sehir and Turyol use different ones.
Known as place where people fish and to get fish sandwiches, there are ferries and boat trips here as well
Its the gateway to Istanbul, the Golden Horn and the Bosphorus. You can get ferries to multiple destinations within Istanbul and Bosphorus cruise tours as well. Its an amazingly bustling, busy and vibrant pier. A central hub in your travel plans for seeing Istanbul.
