We went to the spice garden at Ponda, they have 2 elephants, one to ride, and one to wash. It is IR500 to ride and IR600 to wash. We went back for a second visit while we were there, and the family insisted we stayed for lunch (vegitarian as they are Hindu) and refused to let us pay, even though we had had two glasses of lemon grass tea, four bottles of mango juice and two lunches with dessert.
They are a very nice family, their e-mail address is;

Just ask any of the taxi drivers to take you to the tropical spice plantation, I think the place is called Arla-Keri, Ponda, Goa.
Have a happy time there, we did.
