There must have been at least 6 boats with over 100 persons (mainly from the cruise ships in town) to visit the sting rays. You can just wade in the water or snorkel a bit, but with too many people it is virtually impossible. The area is also roped off. The stingrays don’t seem to mind and glide round the many people in the water. There must have been about a dozen. The guides allow you to hold them in your arms. Obviously nobody trot on them and nobody got hurt!
