Pro tips
Footwear is Fundamental
Because you'll be on your feet a lot, good quality, comfortable, and waterproof walking shoes are non-negotiable. Break them in before you go!
Respectful Dressing for Mosques
When visiting mosques, both men and women should dress modestly. Women should carry a headscarf to cover their hair, and shoulders and knees should be covered for both genders. Some mosques provide covers, but it's better to be prepared.
Be Prepared for Crowds (Though Fewer Than Summer)
While April is less crowded than peak summer, popular attractions like Hagia Sophia and the Grand Bazaar will still draw a crowd. Arrive early to beat some of the rush.
Carry Cash for Small Purchases
While credit cards are widely accepted, having some Turkish Lira on hand for street food vendors, small shops, or tipping is always a good idea.
