If you are in Cochabamba and you want to run out your kiddos energy, this City park is a very good cheap option to do it. Besides swings and slides...they have a small pool, a few mechanical games, a separate area for kids under 3, a small(very small ;)) artificial lake with little boats to rent and a little train to move you around, you pay extra for most of the options, but it's still cheap. I'm giving them 3 stars because they don't have clean sanitary (a big issue in almost every public place in Bolivia). --Warning-- very crowded on holidays.
