The pavilion is actually located in Westminister CO. We have gone there a few times. Lost of butterfly’s floating and flying around. It is very very warm inside, so best not to go in the middle of summer.
I don’t remember how many different types of butterflies and moths they have, but it was worth the time and trip. If your trying to take pictures, my suggestion would use a burst mode if your camera allows it and also a fast speed. Some butterflies can be seen relaxing on various plants, others seem none stop and always on the move. Kids of all ages really seemed to have fun there. If your in CO and have a little spare time I would recommend this for the family.
I believe they are open every day. To contact them visit there web site at:
