Things to Do in Istanbul in June
This is the first month of summer, and that makes it the perfect time to take a free Istanbul walking tour. Alternatively, a simple walk through one of the many beautiful parks in this city is also an excellent idea!
You might also want to consider a Bosphorus cruise, as the wind out on the water is sure to cool you down on hot summer days.
