Anything to see or do in Hamilton

Hello,

My family and I would pay a short visit to some friend in Hamilton this Sunday. We may have 2-3 hours of free time in the afternoon. So, is there anything for us to see or do during that period?

Thanks.

The Botanic Gardens are probably the only thing within Hamilton - everything else is at least an hour to an hour and a half away.

That definitely would be one choice. Many thanks.

Hamilton Zoo?

Garden is free...:)

Thanks.
