4 days in Istanbul, Turkey in January. Mosques, the Asian side, winter light over the Bosphorus, and the chaos in between

Just wanted to share some pics from my recent 4-day trip in Istanbul. I went this winter and the cold, grey skies made the whole thing feel more real. No sweating tourists in shorts, no queue stretching around Sultanahmet at 11am. Just the city, the weight of history, and an unsettling number of very confident cats.

What actually saved the trip was planning strictly by neighborhood. Istanbul's traffic is a genuine nightmare, Google Maps will say 20 minutes but then two hours later you're still in a taxi. So we did it zone by zone: Day 1 in Sultanahmet, Day 2 Topkapi + Galata, Day 3 Dolmabahçe, Ortaköy and the crossing to Asia, Day 4 the Golden Horn,Balat, Süleymaniye and Pierre Loti. Now, I'll explain a little bit more about the photos I share:

Photo 1: Hagia Sophia (Ayasofya) Interior, Sultanahmet: Those enormous green roundels with "Allah" and "Muhammad" in gold calligraphy hanging from a Byzantine dome. Since 2024, tourists visit from the upper gallery (ground floor is reserved for worship) and entry is now €25. Book in advance, the queue without a ticket in January was already 45 minutes.

Photo 2: Blue Mosque (Sultan Ahmed Mosque) Courtyard, Sultanahmet: Everyone talks about the interior. The courtyard on a cold January morning with barely anyone around is the better experience. That scaffolding on the left is ongoing restoration, the mosque is fully open.

Photo 3: Yeni Cami (New Mosque) Exterior Courtyard, Eminönü: Right next to the Spice Bazaar and criminally overlooked. The domed ablution fountain in the centre, the cascading smaller domes behind it, most people walk straight past this heading for the Bazaar. Don't do this.

Photo 4: Yeni Cami (New Mosque) Interior, Chandelier and Dome, Eminönü: The interior matches the exterior promise. Rows of hanging glass lamps, Iznik tile panels, light flooding through dozens of windows. Free entry. Built in the 17th century, so the "New" in the name is Istanbul's longest-running joke.

Photo 5: Topkapi Palace Harem Corridors, Sultanahmet: 16th-century Iznik tiles in remarkable condition and an atmosphere that genuinely feels sealed off from time. No phone signal in here, I strongly recommend to download your audio guide before entering. Go first thing, tour groups fill it fast.

Photo 6: Dolmabahçe Palace Gardens, Beşiktaş: The last sultans built a European-style palace on the Bosphorus to compete with Versailles. Photography is strictly prohibited inside, so this garden shot is all I've got. Get there at 9am, the queue by 10:30 is brutal.

Photo 7: Ortaköy Mosque on the Bosphorus, Ortaköy: After visiting the mosque,, get a kumpir (giant stuffed baked potato) from the street stalls right next to the mosque and eat it with the bridge in view. That's the correct Ortaköy experience.

Photo 8: Galata Tower Close-Up, Karaköy: Medieval Genoese stone, built in 1348. The 360° view from the top is worth it. In winter, book the 13:45 slot if you want decent light before it drops.

Photo 9: Street Market Near the Grand Bazaar, Eminönü / Fatih: This is where locals actually shop. The Bazaar itself has gotten very touristy and expensive, come out here to see the real city moving.

Photo 10: Balat Antik Kafe, Umbrella Street, Balat: Rainbow umbrellas suspended over a little market courtyard in the old Jewish quarter of the Golden Horn. Sounds kitschy, works in person. Budget a full afternoon, the uphill backstreets of Balat and Fener are worth the legs.

Photo 11: Fishermen on the Bosphorus Shore, Üsküdar, Asian Side: Three guys fishing in the cold with a mosque and a cargo ship behind them, Hagia Sophia faintly visible across the water. This is why you cross to Asia. The public ferry from Eminönü costs about 35 lira on your IstanbulKart and the crossing itself is half the experience.

Photo 12: View from Süleymaniye Mosque Terrace over the Bosphorus, Fatih: Many locals rate Süleymaniye above the Blue Mosque. Free entry, and at 9am in January it's almost entirely locals at morning prayer. The winter blue-grey light over the Bosphorus from this terrace is a proper moment.

Photo 13: Istanbul Night Skyline from the Bosphorus with Ferry Crossing: Taken from the public ferry coming back from the Asian side, the mosques along the European ridge lit up in gold. Skip the tourist cruise if budget is tight, just take the regular Şehir Hatları ferry at dusk on your IstanbulKart.

Photo 14: Taksim Mosque at Night, Taksim Square: Opened in 2021, right at the top of Istiklal Avenue. At night the domes and carved stone arches glow amber against a black sky. A very different energy from the Ottoman mosques, modern, confident, lit up like a statement.

Photo 15: Süleymaniye Mosque Exterior, Fatih: Designed by Mimar Sinan for Suleiman the Magnificent in the 16th century. Start Day 4 here at 9am. Free entry, and the bare winter trees make the minaret look even taller than it is.

Photo 16: Istanbul Street Cat, Balat / Fatih Area: Sitting behind iron railings in Balat, completely unbothered, watching the street with the expression of someone who owns the place. He does. Istanbul has an estimated 100,000+ street cats, fed and cared for communally by residents. You will stop to pet at least six of them. There is no avoiding this.

I'll also share some practical tips that I found interesting if you're interested in visiting Istanbul:

Beat the crowds (even in winter): Hagia Sophia at 10am is still a wall of people. Be there at 9am when it opens. Same for Topkapi, the Harem fills up fast. Entry to Hagia Sophia for foreign tourists is around €25 now (upper gallery only), and the queue without a pre-booked ticket can cost you an entire morning.

Transport: Get an IstanbulKart the moment you arrive. It works on every metro line, tram, Marmaray train, bus, and the public Bosphorus ferries. The ferry from Eminönü to Üsküdar or Kadıköy on the Asian side costs the same as a metro trip (around 35 lira) and is genuinely one of the best experiences in the city. Don't take taxis between major sights. The traffic will break you.

Money & Scams: I recommend not change money at IST or SAW airports, the rates are predatory. Bring euros and change them in the city. Best rate I found was at Angun Döviz, near the Grand Bazaar, real mid-market rate on screens, no hidden fees. Always carry cash for street food and market stalls. When recharging your IstanbulKart at metro machines, don't accept help from anyone who approaches you. It's a known scam where they swap your topped-up card for an empty one while you're distracted (this happened to me and it wasn't pleasant :( )

The Local Bosses: Wherever you go in Istanbul in winter, the cats have already claimed the best spot. There's one asleep on a tram seat, three running the spice bazaar, a very serious tabby managing operations near Topkapi. Locals feed them daily, build them shelters and split vet bills between neighbours. They're treated with genuine respect, and they know it.

Happy to answer anything in the comments: how to structure it if you only have 3 days instead of 4, entry costs, which airport to use, or what to cut if time is tight.
