How is the butterfly garden?
I would skip this, nothing special. The "farm" is a probably on a total of half-an-acre and is a single-level house that serves as an entrance and a museum of sorts with a large tropical garden (with netting) in which a variety of live butterflies fly around.
The museum consists largely of a display of preserved butterflies and the requisite explanations of the life cycle of a typical butterfly etc.
I was in and out in 45 minutes (substantially helped by the fact that I read everything, every word, every minutiae, on display) - semi-fun for kids though
