On Saturday, April 27, we will host an all-day City Nature Challenge observation event on our nature trails!

Stop by anytime, and encourage your friends and family to join us!

The City Nature Challenge is a world-wide project to document urban biodiversity and engage city residents in the nature around them. The project is framed as a competition between cities to see which can make the most observations, identify the most species, or have the most participants. Butterfly Pavilion is pleased to participate this year in the Denver Metropolitan Area City Nature Challenge.
