Why Visit Nicomedia? #

Ancient significance and a sheltered gulf setting draw interest to Nicomedia’s modern counterpart, İzmit. Roman and Byzantine ruins point to its imperial past, while landmarks such as the İzmit Clock Tower and Ottoman-era bathhouses reflect later layers of history. Seafood restaurants and bustling bazaars along the Gulf of İzmit make urban wandering rewarding. Close proximity to Istanbul offers easy access for travelers who want history without the megacity crowds.

Who's Nicomedia For?

Business

Modern İzmit (ancient Nicomedia) is an industrial and logistics hub east of Istanbul with good highway and port links. The Kocaeli Free Zone and practical conference hotels make it a solid choice for trade visits and corporate stays.

Nature Buffs

The Marmara coastline and Seka Park give pleasant seaside promenades, while Yuvacık reservoir and the Kartepe foothills are close for lakeside picnics and birdwatching. Facilities are comfortable, though specialist eco‑tourism services are limited.

Couples

The İzmit waterfront and small seafood restaurants near the promenade suit relaxed dinners. Weekend escapes to Kartepe provide mountain views and ski options in winter, ideal for short romantic breaks from Istanbul.

Adventure Seekers

Kartepe sits under an hour away for summer hiking and winter skiing; nearby forests have basic trails for day hikes. Outdoor operators are modest in number, so arrange guides and equipment ahead for more technical routes.

How to Get to Nicomedia

Nicomedia is the ancient name for the modern city of İzmit in Kocaeli Province. The city is best reached via nearby airports (Cengiz Topel for limited domestic flights, or the larger Istanbul airports) and by rail or intercity coach to İzmit Garı and the İzmit Otogarı.

By Air

Kocaeli Cengiz Topel Airport (KCO): Located in Kocaeli province, Cengiz Topel is the closest airport to modern İzmit and handles a limited number of domestic flights. From the airport you can take a taxi to central İzmit (approx. 30-45 minutes); expect an approximate fare of 300-450 TRY depending on traffic. There are sometimes scheduled shuttle buses or private transfer services to Körfez/İzmit - check carriers and timetables in advance.

Sabiha Gökçen International Airport (SAW): Sabiha Gökçen (on Istanbul’s Asian side) is the most convenient major airport for reaching İzmit. By car or taxi it takes roughly 60-90 minutes to central İzmit (depending on traffic); taxi fares typically range from about 600-900 TRY. You can also combine public transport: Havabus/Havaist or local buses to Pendik/Gebze and then regional trains or buses to İzmit (total journey often 90-120+ minutes; combined fares typically 50-150 TRY depending on choices).

Istanbul Airport (IST): Istanbul Airport is larger but farther away (generally 90-150 minutes by road to İzmit). Taxis from IST are expensive for this distance (often well over 1,000 TRY). A more economical option is to take an HAVABUS/Havaist or shuttle into central Istanbul or to the Marmaray/M7/rail connections, then transfer east via Marmaray/ada-Express or intercity bus to İzmit - total travel time typically 2-3+ hours and combined costs vary widely (often 100-300 TRY depending on connections).

By Train & Bus

Train: İzmit has a main railway station, İzmit Garı, on the Istanbul-Ankara corridor and is served by regional services (including the Ada Express Pendik-Adapazarı service) and other TCDD regional trains. Typical journey times: from Pendik (Istanbul) to İzmit by regional train about 45-70 minutes; from Adapazarı/Arifiye short regional hops under 30 minutes. Fares on regional trains are modest (often in the tens of TRY - check TCDD for exact current prices and timetables).

Bus: İzmit Otogarı (the city’s intercity bus terminal) connects to Istanbul (Esenler Otogar), Ankara and many Anatolian destinations. Buses from Istanbul’s Esenler terminal to İzmit typically take 90-150 minutes depending on route and traffic; fares commonly range from ~60-150 TRY for intercity coaches. Within the Kocaeli metropolitan area, municipal buses and dolmuş (shared minibuses) link İzmit centre to surrounding towns; you’ll generally pay with the KocaeliKart or exact cash fares for dolmuş.

How to Get Around Nicomedia

Izmit (Nicomedia) is easiest to navigate by a mix of regional rail or intercity coach for arrivals and municipal buses, dolmuş or taxis for local travel. Trains and the Otogar are the most reliable ways to avoid peak‑hour road congestion; for short distances the city centre is very walkable.
