A weekend is enough time to fall for Istanbul without trying to see all of it. This relaxed two-day plan sticks to the historic peninsula and a leisurely stroll across to the modern side, leaving plenty of room to linger over tea and take in the views.
Ease into the day with a late breakfast near Sultanahmet before wandering into the Hagia Sophia, taking your time under its vast dome rather than rushing through. Just across the square, step into the Blue Mosque, then rest your legs in the cool, atmospheric Basilica Cistern and take a slow loop around the nearby Hippodrome of Constantinople. In the afternoon, visit the Topkapi Palace, pacing yourself through the courtyards and treasury rather than seeing every room. As evening falls, settle into a relaxed dinner at one of the rooftop restaurants overlooking the Bosphorus in Sultanahmet, where the mosques light up after dark.
Start with a slow morning wander through the covered lanes of the Grand Bazaar, browsing rather than buying, then cross the Galata Bridge toward the Galata Tower for panoramic views over the old city. From there, drift down Istiklal Avenue, stopping wherever a cafe or shop catches your eye, before arriving at lively Taksim Square. If energy allows, spend a quiet hour at the Dolmabahçe Palace along the water in the late afternoon, then close the weekend with an easy evening walk and a simple meal in one of the side streets off Istiklal.
