SAN DIEGO ZOO
1. Panda Trek
The giant panda superstars spend most of their day eating bamboo, oblivious to the millions of adoring fans that line up for hours for a glimpse or to watch them via a 24-hour panda cam. Six panda births have occurred at the zoo in the last nine years, most recently male Xiao Liwu in July 2012. The area also features golden-hued takins, considered national treasures in China along with the pandas.
