Your guides take every measure to ensure that you and your family are in a safe situation while paddling. You will paddle large, expedition-style sea kayaks. Their size, girth, and weight make them very stable to paddle! But still, as with all adventure travel, there is an inherent risk that comes along with this sort of travel, as well as multiple external factors and variables that are outside of our control.
Your guides have never experienced a situation in which a whale has harmed a kayaker in the water. The whales are very aware of their surroundings, and you will maintain a safe distance at all times.
