The highlights
These picks come out of our full Istanbul: Bosphorus & Byzantine guide - each one earns its place on a first visit.
1. Hagia Sophia
The 1,500-year-old basilica-turned-mosque with its floating dome - visit early and look up through the scaffolding-free angles.
2. Blue Mosque
Still an active mosque with Iznik tiles by the ten thousand; closed at prayer times, modest dress required.
3. Topkapi Palace
Ottoman courts, the treasury and the harem (separate ticket) over the Bosphorus confluence.
4. Basilica Cistern
A sunken forest of 336 Byzantine columns with medusa-head bases, cool on any hot afternoon.
5. Bosphorus ferry
The commuter ferry to Kadikoy is the cheapest cruise in Europe - seagulls, tea in tulip glasses, two continents in 25 minutes.
Practical tips
Start sightseeing early - the first hours at any famous site are quieter, cooler and better lit. Keep water and a offline map handy, and check opening days: opening days and access rules vary by site. For timing the whole trip around weather and crowds, see when to visit Istanbul: Bosphorus & Byzantine.
- The Museum Pass Istanbul skips ticket lines at the peninsula sites where queues stack up.
- Hagia Sophia's tourist entrance now has a fee and a separate door; visit early or in late afternoon to avoid prayer crowds.
- The public Bosphorus ferry beats dinner cruises: a commuter sailing at sunset costs almost nothing.
- The Grand Bazaar closes Sundays; the Spice Bazaar does not — plan the shopping day accordingly.

Four: two for the historic peninsula, one for the Bosphorus and Karaköy-Balat, one for museums and a hamam. Anything less forces the bazaar and the basilica into one exhausting day.
