Please see travelogue for more pics of the Butterfly Pavillion. I don't have a very sophisticated camera, so the shots aren't that great. But, the Butterfly Pavillion is fantastic! It's like a green house jungle. There are big and small butterflies whirling around your head, even the big blue ones! It was very nice and relaxing too.... There are other exhibits too... I would recommend seeing this if you are in Boulder/Denver!
