Kadıköy-İDO is the main transport interchange on Istanbul’s Asian side, where the M4 metro line terminates at the Kadıköy metro station. Opened in 2012, this underground station sits beneath Haydarpaşa Rıhtım Caddesi (the waterfront road) and forms part of a larger connected hub that includes the İDO ferry terminal, the T3 heritage tram, and direct access to Kadıköy’s shops and restaurants.
The station is 34 meters underground and serves as a major junction for visitors heading to the ferries, the historic neighborhoods, or onward to Sabiha Gökçen Airport on the airport-bound M4 line. Nearly all transport in Kadıköy—metro, trams, ferries, buses and minibuses—converges here, making it the primary entry point for the district.

Why Visit Kadıköy-İDO?
This is where you change between the metro and ferries, between the metro and the vintage Moda tram, or between the metro and İETT buses. The station connects seamlessly to the İDO ferry terminal for seabus journeys to Yenikapı, Bakırköy, Bostancı, and destinations across the Marmara Sea. If you’re taking a ferry to the European side, exploring Kadıköy’s markets or waterfront cafes, or catching a ferry to Bursa, you pass through here. It’s also the western terminus of the M4 line, so all trains heading toward Sabiha Gökçen Airport depart from this station.
Highlights of Kadıköy-İDO
Underground Metro Platform
The Kadıköy metro station sits 34 meters underground on a single island platform served by the M4 line. The station opened on 17 August 2012 along with 15 other stations on the Kadıköy-Kartal section. Inside, six escalators and six lifts move passengers between the platform level and the entrance concourse. The station architecture uses a cut-and-cover construction method, with walkways extending east and west to reach different parts of the connected transport hub above.
Tip: Use the western exit (labeled 4) if heading toward the market; use the eastern exit (labeled 3) for ferry and tram connections.
İDO Ferry Terminal Connection
The İDO Kadıköy Terminal, opened in 1992, sits directly above and adjacent to the metro station. It operates seabus ferries (fast catamarans) to Yenikapı, Bakırköy, Bostancı, and across the Marmara Sea to Bursa, Yalova, and other destinations. The ferry terminal is one of four landing points in Kadıköy Harbor and is accessible through clearly marked exits from the metro station with about 50 meters of walking.
Tip: Ferry schedules are posted at the terminal; book ahead in summer for long-distance Marmara routes.
T3 Kadıköy-Moda Heritage Tram Connection
The T3 tram line, which operates the nostalgic open-sided tram cars on a vintage narrow-gauge track, has its own station (Kadıköy İDO Tram Station) at ground level near the metro exit. The tram runs at sidewalk level—not in a separate right-of-way—connecting Kadıköy to the waterfront suburb of Moda. It opened on 1 November 2003 as part of the city's heritage transport network.
Tip: The T3 tram is scenic but slow; it's a leisure ride rather than rapid transport. In summer the open sides let in sea breeze; in winter they can feel exposed.
Wheelchair Access and Lifts
The metro station is wheelchair-accessible with six lifts serving the platform and entrance levels. The accessibility applies to the metro station itself. Ferry terminal accessibility and tram station accessibility should be confirmed separately; the tram platform is at street level with no boarding aids.
Tip: Allow extra time if using lifts during peak hours; plan your journey outside rush hours for smoother transfers.
Metro Connections to Four Exits
The Kadıköy metro station has four main exits: Exit 1 (IDO İskelesi, the ferry pier); Exit 2 (Moda, the heritage tram); Exit 3 (Bahariye Street, leading to shops and restaurants); and Exit 4 (Haldun Taner Stage and Marmara Park). These lead to pedestrian underpasses extending into the surrounding district, reducing surface congestion and protecting from weather.
Tip: Orient yourself by exit number before you arrive; signage inside the station is clear but the district above is labyrinthine.
Integration with Bus and Minibus Network
The station sits at the hub of Kadıköy's bus network, with İETT city buses and private minibuses (dolmuş) operating from stops near the ferry terminal and main street exits. Routes serve all neighborhoods of the Asian side and connect to distant areas like Çekmeköy, Bağlarbaşı, and Ataşehir. The Metrobus rapid bus line also stops nearby.
Tip: Bus route numbers are posted at stops; the Kadıköy hub is crowded at rush hours (07:00-09:00 and 17:00-19:00).
Atmosphere
Kadıköy-İDO feels like the living room of the Asian side. On weekday mornings it fills with commuters; evenings and weekends bring shoppers and leisure travelers. The station platforms are modern and clean, with fluorescent lighting. Belowground, it’s efficient and busy but not uncomfortably crowded outside peak hours.
Above, the tram station and ferry terminal open onto the waterfront and the market district. The sea breeze, the smell of grilled fish from nearby restaurants, calls in Turkish and English mixing with tram bells—all create the sensory signature of this working waterfront. In summer the tram platform bustles; in winter it quiets considerably but retains its charm.
History of Kadıköy-İDO
The M4 metro line (Kadıköy–Sabiha Gökçen Airport) was conceived as part of Istanbul’s expansion of rapid transit to the Asian side. Originally planned as a light rail system (Harem–Tuzla), the project was integrated into the Marmaray initiative and relocated to begin from Kadıköy. The Kadıköy metro station opened on 17 August 2012 alongside 15 other stations on the 21.7-kilometer first phase of the line, running between Kadıköy and Kartal.
The station’s location was deliberately chosen to integrate with existing transport: the ferry terminal above (opened 1992) and the T3 heritage tram (opened 2003). The metro was built 34 meters below street level using cut-and-cover excavation. Four primary exits were designed to distribute passenger flow to different parts of the district—the ferry piers to the north, the market and shops to the east, the waterfront to the west—reducing surface congestion.
In subsequent years, the M4 was extended further east. By 2022, the line had expanded to 23 stations, reaching Sabiha Gökçen Airport. Kadıköy remains its only terminal on the western (Kadıköy) end, making it the crucial entry point for all eastbound M4 traffic.
Tickets and Booking for Kadıköy-İDO
The M4 metro runs daily from 06:00 to 00:04 (midnight). Foreign visitors can purchase single journey tickets at ticket machines or from the ticket booth. Most visitors use the İstanbulKart (a rechargeable transit card), which is cheaper per journey and works on metro, tram, bus, ferry and minibus throughout Istanbul. Cards are sold at newsstands and metro stations and can be topped up instantly. Payment by contactless debit or credit card (Apple Pay, Google Pay) is also accepted at some stations, though cash fares require cards.
Fares and payment details change regularly. Check the official Metro Istanbul website (metro.istanbul) for current rates and accepted payment methods. Peak hours are 07:00–09:00 and 17:00–19:00; services are less crowded outside these times.
How to Get to Kadıköy-İDO
By ferry: If arriving from the European side, disembark at the İDO Kadıköy Terminal (ferries from Yenikapı, Bakırköy) or Kadıköy Pier (Şehir Hatları ferries), both within 100 meters of the metro station.
By foot: The station exits open directly onto the waterfront district. Exit 1 leads to the ferry terminal; Exit 2 to the Moda tram and waterfront restaurants; Exit 3 to Bahariye Street (shops and cafes); Exit 4 to the Haldun Taner stage and parks. All exits are clearly marked underground.
By tram: Arrive at the ground-level T3 Kadıköy İDO Tram Station and descend to the metro platform via stairs or the pedestrian underpass.
By bus: İETT and minibus stops surround the station. The main bus hub is adjacent to the ferry terminal.
Accessibility
The metro station is fully wheelchair-accessible. Six lifts connect the platform level to the entrance concourse, and an additional lift at one exit connects to street level. The entrance areas have level access or shallow ramps. Tactile guidance and audio announcements are available on trains. The station was built to modern accessibility standards.The ferry terminal above has step-free access but its boarding arrangements vary by vessel and sea conditions; arrive early to coordinate with staff. The tram platform is at street level but has no boarding assistance or wheelchair spaces.
Food Nearby
The station exits open directly onto the Kadıköy waterfront district, famous for fish restaurants, kebab shops, and cafes. Within 100 meters you'll find casual seafood grills (meyhane-style establishments where you choose from displays of fish), street vendors selling mussels and sandwiches, and Turkish tea gardens. Restaurants like Pandeli and Hamdi offer sit-down dining with views. Markets selling street food, pastries, and prepared dishes operate daily around Bahariye Street.
What to Bring
An İstanbulKart (rechargeable transit card, sold at the station). Comfortable walking shoes—transferring between exits and walking to ferries or shops involves several hundred meters. In summer, sun protection; the ferry terminal is exposed to strong sun. A lightweight jacket for air-conditioned metro cars and for ferry wind. Small bills or coins are useful for market purchases but not needed for transport.
Photography Rules
Photography is permitted throughout the metro station. Indoor flash photography should be used respectfully during crowded times. The heritage tram platform and waterfront offer good photo opportunities; ask permission before photographing people. Drones are not permitted in the station or ferry terminal. Tripods are impractical in crowded areas.
Family Suitability
Entirely suitable for families. The metro is modern, clean, and organized. The station is pram-friendly with wide corridors and lifts, though navigating multiple exits with luggage or strollers requires planning. Children enjoy the heritage tram ride to Moda (20 minutes); the open sides provide a novel experience. The adjacent waterfront and market attract families. Ferry rides to Marmara destinations are feasible with children but require patience for embarkation. Peak commuter hours (morning and evening) are less pleasant with young children due to crowding.
Istanbul Vibes Tips
- Arrive at the ferry terminal 20–30 minutes before departure, especially for Marmara routes in summer; queues form quickly.
- The station's four exits serve different purposes. If you're unsure of your destination, ask at the information booth before ascending (though not all exits have staffed booths).
- The T3 heritage tram is charming but moves at walking pace; use it for sightseeing, not for speed. A full round trip to Moda takes 1 hour.
- Ferries to the European side (Yenikapı, Bakırköy) depart frequently but fill in summer; single-journey tickets are sold at the terminal but booking ahead online (ido.com.tr) is safer for busy periods.
- Avoid the station 07:00–09:00 and 17:00–19:00 on weekdays if you want a pleasant experience; outside these windows, it's calm and navigable.
- Keep the metro line map with you: the M4 terminus here can feel confusing to new visitors. Exit numbers and clear signage help, but orient yourself by your intended exit before boarding.

FAQ: Kadıköy-İDO
Is Kadıköy-İDO a single station or multiple stations?
It's a connected transport complex: the Kadıköy Metro Station (underground M4 line), the Kadıköy İDO Tram Station (surface T3 heritage tram), and the İDO Ferry Terminal above. They're all within 50–100 meters and share exit corridors, so passengers typically experience them as one hub. Tickets are separate for each mode.
How do I take a ferry from the metro station?
Exit the metro using Exit 1 (İDO İskelesi) or follow signs for the ferry terminal. Walk through the pedestrian underpass or at street level to the terminal building.

Allow 20–30 minutes for the whole process, especially in summer.
What is the T3 heritage tram and is it part of the metro?
The T3 is a separate, vintage open-air tram line that runs on narrow-gauge track at street level between Kadıköy and Moda. It is not part of the M4 metro; tickets are separate. It's a scenic, slow leisure ride (20 minutes round trip). Exit the metro at Exit 2 (Moda) to connect.
Can I use my İstanbulKart on ferries?
Yes. The İstanbulKart works on İDO ferries and Şehir Hatları ferries. Tap the card at the gate in the terminal. Fares are cheaper with a card than cash. Top up your card at metro station machines or newsstands.

Trains run daily from 06:00 to 00:04 (past midnight). During peak commute hours (07:00–09:00 and 17:00–19:00), trains come every few minutes. Off-peak service is slightly less frequent. Exact intervals are posted at the station.
Is the metro station accessible for wheelchairs?
