Note: Expect differences in tour durations due to traffic conditions. Participants are required to remove their shoes in order to enter the Blue Mosque. As this tour visits a place of worship, please dress respectfully: no bare shoulders or exposed knees. Should the Blue Mosque be closed to visitors due to religious festivities, you’ll visit another historical mosque. On Sundays, the Grand Bazaar is closed so your visit will be replaced with free time at the Spice Market. In this case, due to the size of the Spice Market, your overall tour duration will be shortened slightly. The "Gallery" section of the Hagia Sophia is not included, but it may be visited during free time. There is approximately 1 1/2 miles of walking over uneven surfaces and some inclines and steps on this tour. This tour will be subject to national and religious festive days due to the closure of the sites and venues during the month of Ramadan, including the Festival Period of Ramadan. Tour is not offered on day one of Norwegian Jade winter sailings.
