The Blue Hole river tubing experience is very safe. The water is generally very shallow and most adults will be able to stand without problem. There is a portion of the river with small rapids, but other than that, the river is quite gentle. You will also be accompanied by experienced tubing guides who will steer and keep an eye on you the entire time. Nonetheless, it's highly recommended that you know how to swim if you plan to take this tour.*This tour is not recommended for pregnant women or those with physical limitations.
