There are no two ways about it: Kids love swimming.

Lake swimming is perfect when the beach or the pool is too crowded, or when you just want to mix it up a bit. There are quite a few lakes in the Philadelphia area that offer great little beaches, picnic areas, and, of course, swimming. As an added bonus, most of these lakes are located in state parks, which offer lots of other great activities, including camping and hiking. So get your bathing suits on, load up the car, grab the sunscreen, and head out to one of these great local swimming lakes.
