Since it is an open-air experience, and you will be high up in the air with lots of tourists below, it is better to wear appropriate clothing. Riders must wear footwear at all times. However, if you reach the attraction in flip-flops, they will provide you a pair of lace-up shoes for the flight duration.  Your flip-flops and other loose articles such as sunglasses, etc., will be kept in a bag and strapped to you on the zipline.
