Weekend Break From Mumbai

I have been doing some vacation research. Some place near Mumbai for a weekend break. I am looking for some quiet time with nature and it seems Matheran is perfect. I don't know if the place is as good is it's on the travel brochure but I like the idea of 'no motor vehicles allowed' in this place. Yes, it seems that no motor vehicles are allowed in the tiny hill station of Matheran which is near Karjat on the Mumbai Pune highway. That's peach and quiet! I can also fulfill my dream of riding a toy train too. I don't have to go all the way to Darjeeling or Simla.
