Gaziantep makes a rewarding short break with museums and bazaar walks between meals. Leaving room for the next dish is part of planning the day.
🍽️ Spread beyran, katmer and baklava across separate stops instead of trying everything at once.
🏛️ Give the Zeugma Mosaic Museum time for an unhurried visit.
🛍️ Browse handicrafts in the old bazaar and pause for coffee.
💡 Excursions such as Rumkale need their own transport and time; they are not a quick extension of a central walk.
