The butterfly house is really well situated to the falls and is an easy commute. The butterflies and loose and flying around whilst you walk through them so it's very special to see. Our 20 month old son really liked the experience. Quite a small space but the exhibition at the end with turtles, snacks etc was an added bonus. Situated amongst the botanical gardens which are nicely kept and no doubt lovely to see in the summer. For a 45 minute activity 15 dollars per adult (plus tax) seemed a little much but a great experience.
