For safety reasons Camp Carnival offers swimming only to children in the 9-11 and the 12-14 year old age groups. This is offered in the form of a Survivor Swim Challenge or Swimming under the Stars. On many ships Carnival's Twister Waterslide will be open during this time for the kids only. Depending on the class of ship there may be a children's wadding pool also available, this will be open for parents to use at their leisure with their children.
