With sunshine sticking around and weekend calendars filling up, it’s officially the season for outdoor adventures. While beaches and hiking trails tend to steal the spotlight, there’s another nature-filled experience that’s well worth adding to your list: walking among hundreds of free-flying butterflies.
If you need a little extra motivation, one of California’s most popular butterfly sanctuaries has just received national recognition. The Sprague Butterfly Pavilion at the Santa Barbara Museum of Natural History was recently named the third most beautiful butterfly pavilion in the country by USA TODAY 10Best Readers’ Choice Awards, a ranking based on expert nominations and thousands of online votes.
One of California’s most magical summer experiences
Home to the museum’s seasonal Butterflies Alive! exhibit, the Sprague Butterfly Pavilion transforms into a living tropical garden every summer. Visitors stroll through an airy outdoor enclosure where around 1,000 live butterflies representing more than two dozen species from Costa Rica flutter freely among hundreds of flowering plants, a tranquil pond and nectar-rich gardens designed specifically for pollinators.
One of the highlights is the emergence chamber, where guests can observe butterflies completing one of nature’s most remarkable transformations. Depending on your timing, you may even witness an adult butterfly emerging from its chrysalis and slowly unfurling its wings for the very first time before taking flight.
The pavilion itself is as thoughtfully designed as the exhibit it houses. Opened in 2018, the structure was built using local Santa Barbara sandstone and sweeping steel ribs that echo the shape of butterfly wings.
Rather than using sharp right-angle corners, the pavilion follows soft, flowing curves inspired by butterfly behavior, since butterflies naturally struggle to navigate 90-degree turns.
Although the museum first launched its butterfly exhibit in 2001, the construction of the permanent Sprague Butterfly Pavilion elevated the experience into one of California’s premier seasonal attractions.
Today, the butterflies are sustainably raised on family-run farms in Costa Rica, supporting conservation efforts while giving visitors an unforgettable close-up look at some of the world’s most colorful pollinators.
