On the corner of Beekman Street and Division Street in Saratoga is park called West Side Rec. This is probably one of my favorite summer time spots because in addition to many shaded areas and a decent playground, this park has water! A large interactive fountain sits in the middle of the grass, a refreshing invitation for hot, sticky kids. This park is a good size, and as I mentioned, has plenty of shaded areas, some benches and picnic tables. The playground equipment is basic and there is a good sized sand box. There is a bathroom but it is a bit of a walk and a small step up from a porta potty.
Despite that, West Side Rec is a nice spot and well worth a visit. Fountain opens for business after Memorial Day and closes shop after Labor Day.
