Butterfly Pavilion is a unique invertebrate zoo and nature center located in Westminster, Colorado, just 15 minutes from downtown Denver. The facility is home to over 1,800 free-flying butterflies representing more than 200 species, displayed within the immersive Wings of the Tropics tropical butterfly house. Beyond butterflies, visitors explore Water's Edge aquatic exhibits, the Colorado Backyard nature area, and Nature Play spaces, and can enjoy a personal encounter with Goldie, the resident Golden Knee Tarantula. As a nonprofit zoo, Butterfly Pavilion conducts meaningful conservation work protecting pollinators and invertebrate habitats through local Colorado projects and international partnerships, including firefly conservation initiatives. Educational camps, yoga events, and hands-on learning experiences make it an inspiring destination for families, students, and anyone curious about the remarkable world of invertebrates.
