To celebrate National Hispanic Heritage Month, the Butterfly Pavilion is offering $2 off both kids and adult admission on Sunday, October 4. That works out to $4 for kids and $9 for adults that day. Check out the Invertebrate World exhibit, 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. Children under two always get in for FREE. The pavilion is open from 9 a.m. to 5 p.m. 6252 W. 104th Ave., Westminster, 720-974-1878.
