Our first 48 hours guide covers the essential two days: the historic peninsula and the Bosphorus and Beyoğlu. If you have two more days, this is where they go, and none of it repeats what those first two already cover.

Days 1 and 2: the essentials

Follow the 48-hour guide exactly as written: Hagia Sophia, the Blue Mosque, Topkapi Palace and the Basilica Cistern on day one, the Bosphorus and Beyoğlu on day two. What follows here picks up where that guide leaves off.

Day 3: the Asian side, properly

Where day two only had time for a quick ferry over for dinner, day three gives Kadıköy the morning and afternoon it deserves. Start at the Tuesday or Friday market if your dates line up, wander the bar and record-shop streets around Kadife Sokak, and walk south along the water to Moda for the best sunset view of the old city skyline from across the water. Cross back to Üsküdar in the late afternoon for the Maiden's Tower view and the İskele Mosque, both far less crowded than their European-side equivalents. This is also the day to consider the Princes' Islands instead, if a full day trip off the peninsula appeals more than a slower afternoon in Kadıköy; it's a genuinely different day, not an add-on to this one.

Day 4: Balat, Fener, and the Bosphorus villages

Morning in Balat and Fener, Istanbul's most photographed streets and for good reason: colourful Ottoman-era houses on steep lanes, the Bulgarian St. Stephen Church built from cast iron, and considerably fewer tour groups than the historic peninsula. Break for lunch in the neighbourhood rather than heading back to Sultanahmet for it.

In the afternoon, head up the European shore to Ortaköy and Bebek. Ortaköy's Bosphorus-front mosque and Sunday craft market are the draw, and it is the best spot on this side of the water for a sunset drink with the Bosphorus Bridge lit up behind it. Bebek, a short walk or bus ride further north, is the upscale, waterfront version of the same neighbourhood feel, worth the extra distance if you want fewer crowds. Both are reachable by bus from Beşiktaş; a taxi is easy if you're short on time.

What four days actually costs beyond the first two

Days three and four add mostly transport rather than ticket prices, since none of the above requires an entrance fee beyond the Maiden's Tower if you go inside (a small additional cost, check current pricing at the ticket office). Ferries between the European and Asian sides run a few lira each on an Istanbulkart, and the bus up to Ortaköy and Bebek is the same. If you swap day three for the Princes' Islands, budget for that day trip's own costs, covered in its own guide.

Four days is enough to stop feeling like a tourist and start feeling like you know the city, without needing a full week to get there. If you only get three, keep day three and treat day four as the one to cut, since Balat and the Bosphorus villages reward a slower pace more than they punish being skipped.

Frequently asked questions

Is four days enough to see Istanbul properly?

Enough to cover the major sights, both sides of the Bosphorus, and at least one neighbourhood, Balat or Kadıköy, that most two-day visitors miss entirely. A week lets you slow down further and add a day trip.

What should I add on day three if I've already done the essentials?

Kadıköy and Üsküdar on the Asian side, or a full day trip to the Princes' Islands instead, if you'd rather have a complete change of pace than another afternoon in the city.

Are Balat and Fener worth a full morning?

Yes, and they're considerably less crowded than the historic peninsula covered in the first two days. Go in the morning before the light gets too harsh for photos, and stay for lunch in the neighbourhood.

How do I get to Ortaköy and Bebek?

Both are a short bus ride up the European shore from Beşiktaş, or an easy taxi. Ortaköy's mosque and market come first; Bebek is a further walk or short ride north for a quieter, more upscale version of the same waterfront feel.
