Happy Hollow Park & Zoo, Educational zoo in San Jose, US.

Happy Hollow Park & Zoo is a 16-acre (6.5 ha) zoo and amusement park in San Jose, California. It holds a petting zoo with an animal barn, a puppet theater, an animal hospital with surgery and radiology, and an education center built from hay bales. Rides include the Keep-Around-Carousel with wild-animal seats, the Pacific Fruit Express family roller coaster, and Danny the Dragon, a dragon-shaped rubber-tyred train.

Jaycees members Alden Campen and Ernie Renzel began planning the park in 1956, and the city bought the original 7.5 acres at the north end of today's Kelley Park for $300,000. Happy Hollow opened in 1961. It closed in 2008 for major renovations and reopened on March 20, 2010.

The park's puppet theater stages shows for children, and the education center built from hay bales runs year-round classes for ages 12 months to adult. The animal hospital has indoor and outdoor quarantine, surgery and radiology rooms. A "parallel play area" sits next to the endangered lemurs.

The 16-acre site sits at the north end of Kelley Park in San Jose, with the puppet theater, animal hospital, education center and rides laid out together, so families can move between zoo exhibits and rides on foot. The park closed in 2008 for major renovations and reopened on March 20, 2010.
