we booked the canyon, rafting, jeep, zipline and buggy experience in Antalya.we had an amazing canyon experience a few years ago in Philippines and were looking forward to this.However, on the day we were informed that the canyon event required us to be excellent swimmers who could swim 600m in deep, ice cold water which was very fast flowing. this was NOT mentioned by GrtYourGuide when booking. we therefore had to cancel this event which we paid for.the rest of the events were most enjoyable especially as we had a wonderful and entertaing guide, Captain Hassen
