While you can't beat the beach for having fun.. Manhattan Beach has two large Parks. Live Oak is the place for softball and tennis. There is also a place for little kids to play and a dog run for pups to meet new friends. Polliwog park has a lovely lake and a playground with lots of things to do for the under 5 crowd. Polliwog also has one of the original homes built in Manhattan Beach when the entire city was mostly giant sand dunes..... and speaking of sand dunes.. Sand Dune Park off Bell Ave has one of the last remaining sand dunes in the city. If you are looking for a great workout try climbing the dune a few times.
