Birthdays are always a special day to flutter around with friends and family. And you can do just that on your special day at the Butterfly Pavilion. Admission is just $1 for the birthday boy or girl. (That includes adults, too!) You’ll need to present an ID at the ticket counter. (Note: Regular admission applies to everyone else in your party.) Journey through the Crawl-a-See-Em, hold Rosie (our favorite tarantula), touch a starfish and make your way through a tropical rainforest populated with 1,600 fluttering butterflies. In fact, there are more than 5,000 animals in all. They’re open daily from 9 a.m. to 5 p.m. 6252 W. 104th Ave., Westminster, 720-974-1878.
