British Swim School, Lindenhurst

British Swim School's instructors know that swimming, splashing, diving, and cannonballing are loads of fun. But they also know that swimming is an important survival skill, one that's especially vital for young children. For the last 30 years, they've led lessons that give kids the tools they need to have fun and be safe, too. Swim instruction covers all the basics, including teaching kids how to float on their back—a technique the staff believes is one of the most important water survival skills. Instructors teach students as young as 3 months, and lead small-group classes for adult beginner and intermediate swimmers, as well.
