5 Things to Do in Istanbul (by Season)

1. Hagia Sophia

A place that feels like the heart of Istanbul itself, Hagia Sophia is a famous fusion of history, architecture, and spirituality.

2. Blue Mosque (Sultanahmet Camii)

Facing Hagia Sophia, the Blue Mosque is both a spiritual haven and an architectural masterpiece. Its six minarets pierce the sky, while the interior glows with the soft blue of over 20,000 Iznik tiles.

As one of Istanbul’s most photographed landmarks and one of the most beautiful landmarks in the world, it balances its role as an active place of worship with its draw as a cultural gem. Step inside, and you’ll be enveloped in peaceful silence, broken only by the call to prayer echoing through the domes.

• Best Time to Visit: Spring or Fall (non-prayer hours, especially just after Fajr or mid-morning).

• Why: Avoids midday tourist and prayer crowds. Cooler temperatures are ideal for walking around Sultanahmet Square.

3. Topkapi Palace

Once the very heart of the Ottoman Empire, Topkapi Palace combines luxury with legend. Within its high stone walls lie elegant courtyards and chambers that once housed sultans, concubines, and royal advisors.

The Treasury displays bejeweled daggers and oversized emeralds, while the Harem wing poses a glimpse into palace life hidden from public view. With sweeping views of the Bosphorus and the Golden Horn, it’s a must-visit for history buffs and lovers of architecture.

Wander through aisles of handwoven carpets, glittering lanterns, antique coins, leather goods, and fragrant spices. Or just people-watch over a cup of Turkish tea. Either way, the bazaar is a sensory adventure that tells its own story.

• Best Time to Visit: November to February (weekdays).

• Why: It’s indoors, which is great for colder months. Fewer tourists in winter means easier bargaining and less crowding.
