What We Love
Wings of the Tropics
The main event is, of course, the breathtaking conservatory. As you step through the doors, you’re immediately enveloped in a warm, humid environment filled with tropical plants and the gentle sound of waterfalls. It’s a truly magical experience to have thousands of butterflies from all over the world flying freely around you, often landing on your shoulder or hand for a moment.
You’ll see stunning Blue Morphos, delicate Rice Paper butterflies, and countless other species in every color imaginable. Take your time strolling along the winding paths, and be sure to check out the chrysalis viewing window, where you might be lucky enough to witness a new butterfly emerging and preparing for its first flight. It’s a photographer’s dream and a peaceful escape from the everyday.

Rosie the Tarantula
For those feeling brave, a visit isn’t complete without meeting the pavilion’s most famous resident: Rosie the tarantula. This is your chance to get up close and personal with a gentle giant of the spider world. Staff members are always on hand to tell you all about these fascinating arachnids and guide you through the experience of holding her.
It’s a surprisingly calm and unique encounter that helps dispel many common fears about spiders. Rosie is a fantastic ambassador for her species, and feeling her delicate footsteps on your palm is an unforgettable moment. It’s a great way to challenge yourself and learn to appreciate a creature you might normally shy away from.

Interactive Exhibits
Beyond the butterflies, there’s a whole world of other invertebrates to explore. The “Crawl-A-See-Em” area features a variety of insects, spiders, and scorpions in carefully designed habitats. You can also explore the “Water’s Edge” exhibit, which showcases incredible aquatic life like sea stars, horseshoe crabs, and sea anemones in a large touch tank.
These exhibits are designed to be hands-on and engaging, making learning about these creatures fun and accessible. Knowledgeable staff and volunteers are always nearby, ready to answer questions and share amazing facts. It’s a fantastic way for both kids and adults to connect with the natural world in a meaningful way.

Outdoor Gardens
Don’t forget to explore the outdoor areas! The pavilion has beautiful gardens and a nature trail that highlight local Colorado ecosystems and the pollinators that call them home. It’s a peaceful place to walk around and see how the principles of conservation you learned inside are applied in a natural setting.
The gardens are planted with native flowers and plants that attract local butterflies, bees, and other insects. It’s a great source of inspiration if you’re looking to create your own pollinator-friendly garden at home. It also serves as a lovely, quiet spot to relax after the excitement of the indoor exhibits.

Conservation Mission
One of the best things about visiting is knowing that your ticket supports a vital mission. The Butterfly Pavilion is deeply involved in research and conservation efforts, both locally and globally. They work to protect habitats, study pollinator populations, and educate the public about the importance of invertebrates.
By visiting, you’re directly contributing to these programs and helping to ensure that these incredible creatures will be around for future generations to enjoy. It adds a layer of purpose to your visit, making the experience not just fun, but also meaningful. You leave with a greater appreciation for the small wonders of the world and the people working to protect them.

Atmosphere & Setting
The atmosphere inside the Butterfly Pavilion is one of vibrant, active discovery. The main conservatory is warm and humid, designed to mimic a tropical environment, and it’s filled with the constant, gentle motion of thousands of butterflies. The sound of trickling water and the lush greenery create a serene and transportive setting that makes you feel like you’ve stepped into another world.
In the other exhibit areas, the vibe is more like a hands-on science museum. It’s lively and buzzing with the excited chatter of families and school groups. The layout is open and easy to navigate, encouraging you to move from one fascinating display to the next at your own pace. It’s a welcoming and stimulating environment that perfectly balances education with pure, simple fun.

Value (Is It Worth It?)
A trip to the Butterfly Pavilion is absolutely worth the price of admission. General admission tickets typically range from about $15 to $25, with discounts for seniors and children. While it’s not the cheapest outing, the value comes from the unique, immersive experience you get. There’s nothing else quite like it in the region, and the chance to interact so closely with these creatures is priceless.
Considering that your ticket also supports the facility’s non-profit conservation and research initiatives, it feels like a great investment. You can easily spend two to three hours exploring everything, making it a solid half-day activity. For the memories you’ll make and the education you’ll receive, it’s a fantastic deal for families, couples, or anyone with a love for nature.

Other Considerations
