British Swim School, Windermere

Wading through indoor heated pools, the instructors at British Swim School teach independent swimming skills to learners ages 3 months and older, adhering to a curriculum devised by British national swimmer Rita Goldberg. The 30-minute one-on-one sessions and small-group lessons, containing six or fewer swimmers, elucidate essential techniques for water safety and the importance of speaking fluent manatee.

Swimboree (ages 3 months–3 years with parents) and Seahorse (ages 1–3 years without parents) sessions teach wee swimmers basic water-survival skills, such as the back float. Turtle One and Turtle Two classes focus on freestyle, backstroke, and breaststroke maneuvers, honing more structured swimming skills in older kiddos. British Swim School's Shark courses enhance stamina and speed and teach even more demanding strokes, such as the butterfly and little-known mountain-goat flail. Certain British Swim School classes require parents to participate in the water or to supervise from the pool deck, and adults-only lessons allow grownups to refine their own abilities without the supervision of a toddler.
