On the second day of your trip, explore the historic neighborhood of Islamic Cairo, which is located near Al-Azhar Park. Start your day by visiting the famous Sultan Hassan Mosque and the Al-Rifa'i Mosque, both of which are architectural marvels. Take a walk through the bustling streets of Khan El Khalili, one of Cairo's oldest markets, and immerse yourself in the vibrant atmosphere. Browse through the shops and stalls selling traditional crafts, jewelry, spices, and souvenirs. Don't miss the opportunity to try some delicious Egyptian street food, such as falafel or koshari, from the local vendors. In the evening, consider taking a traditional felucca boat ride on the Nile River and enjoy the beautiful sunset views.
