Antalya's Old Town, also known as Kaleici, is a charming neighborhood with narrow streets and historic buildings. It is a great place to explore on a rainy afternoon, as many of the streets are covered by arches. You can wander through the streets, admiring the Ottoman-era houses and the ancient city walls. There are also many shops and cafes in the area, where you can take a break and enjoy a cup of Turkish tea or coffee.
