New: ranked list of Istanbul's top 25 attractions and month-by-month planning guides for May , June , and July . Pro tip: The Museum Pass Istanbul (€175 / 5 days) pays for itself if you visit Hagia Sophia + Topkapı + Harem + Galata Tower + Chora — and gives skip-the-line at all of them. Buy at any participating museum gate or via the official Müzekart app. What is the best way to see Istanbul in 3 days? Day 1 — Sultanahmet (Hagia Sophia → Blue Mosque → Topkapı → Basilica Cistern, all within 800 m). Day 2 — Bosphorus & Beyoğlu (morning ferry up the Bosphorus, afternoon Galata Tower + İstiklal + Karaköy dinner). Day 3 — Asian side (Kadıköy market + Moda promenade + ferry back at sunset). This sequence covers all UNESCO-listed monuments without backtracking and saves ~3 hours of metro time vs random ordering. Full breakdown in our perfect 3-day Istanbul itinerary . How much does a Bosphorus cruise cost in 2026? The cheapest authentic option is Şehir Hatları's public ferry — €10 for the 90-min short cruise (Eminönü → Üsküdar → Çengelköy) or €35 for the full 6-hour Boğaz Hattı that reaches the Black Sea entrance. Tourist-branded "Bosphorus Tour" boats sold around Eminönü charge €25–40 for the same 90 minutes; private yacht charters start at €350 for 2 hours. Sunset dinner cruises with live music run €70–120 pp. Avoid touts at the pier — buy at the official Şehir Hatları booth or in advance via our private Istanbul tours . Is Hagia Sophia free to enter in 2026? No — since January 2024 foreign visitors pay €25 to access the upper gallery (the only area open to non-worshippers). Turkish citizens and Muslim worshippers entering for prayer enter free via the main ground-floor pra
