We’ve looked at taking a Rick Steves tour to Turkey, but haven’t done so yet. Rick talks about the Galata Mevlevi House Museum, which has Whirling Dervishes once a week (Sundays at 6:00 PM). Its Website is https://muze.gov.tr/muze-detay?sectionId=GLT01&distId=MRK
From the Website, they describe their ceremony (or “ceramony” on the Website), and also the Hodja Pasha one, which they describe as genuine:
Sema Ceramony:
Whirling dervish ceremonies are performed every Sunday at 6PM and duration of the show is 1 hour. Entrance tickets (30.00 ₺) can not be bought at location any-longer and should book online at https://biletinial.com/ but since there are only 150 seats, tickets are usually sold out quickly. Please note that there are no seat numbers, so if you want to view the ceremony from the front rows, make sure you arrive early.
There are only a few genuine whirling dervish ceremonies in İstanbul, Hodja Pasha Culture Center represents the authentic sema ceremony with its mystical journey and gravity, located near Sirkeci tram station T1 (Tram 1).
