Sultanahmet feels like the heart of old Istanbul, with history around every corner, and this relaxed small-group stroll takes you straight to the two biggest stars: the Blue Mosque and Hagia Sophia. You’ll wander the vibrant neighborhood first, admiring the mosque’s cascading domes and famous blue tiles from the inside while your guide shares what makes it special. Then it’s across to Hagia Sophia – that massive dome and golden mosaics still blow people away after all these centuries – hearing stories about Byzantine emperors and Ottoman sultans as you stand right where it all happened. The guide keeps things easygoing, points out hidden details most miss, and slips in tips for good local eats and drinks nearby. Small group means you can actually ask questions and feel the place rather than just ticking boxes. Perfect half-day taste of Istanbul’s soul.
