ESCONDIDO, Calif. — Each year, a section of the San Diego Zoo Safari Park, known as the Hidden Jungle, transforms into a tropical haven filled with hundreds of butterflies fluttering freely among visitors. Bright blooms, chirping birds, and the soft rustle of wings make it clear that spring is in full swing. We're talking about the renowned Butterfly Jungle making its return. The annual event encourages guests to slow down and appreciate the beauty of the small but vital creatures.
