Minors 13 and older don't have to be accompanied by an adult. Kids 12 or younger should have an adult present on site. Roudy teens (with or without supervision) can be asked to leave w/o refund. Must pass lap/swim test to get into the deep section, otherwise they have to stick to the L section, but it's plenty deep on the one side for most people.
They have you swim the length of the pool one time to show you can swim. So not done by age, just your ability to swim length of pool
