What places in mumbai are great for field-trips for kids from 3-5 yrs of age?

Last year I was staying in Mumbai and I remember there was a field trip organised to take kids along with one parent to biscuit factory and Bisleri mineral factory in Andheri. If you are thinking of taking your kids to one then I am sure it will going to be a very enriching experience for them. And I would say not only for them but for you as well if you haven't visited any factory before. When I was first told about these field trip in Mumbai, I felt child like thrill to go there. I am sharing the Facbook page's link where you can find the details as how and where all you can take your kids, and how much it will charge you. Hope it will help. Even if your kid is small like as you mentioned,3, you can yourself accompany him/her, and otherwise also as we can go with our kids paying a nominal charges so that we do not have to worry about their being alone etc. https://www.facebook.com/events/552822291559695/#
