Rome’s only zoological garden opened in 1911, though rennovations have brought this historic zoo up to speed with modern habitat and conservation science. Today, more than 1,000 animals populate the zoo, and you can follow a number of paths that wind through the park and around a small lake to observe lions, elephants, tigers, monkeys, and giraffes, among others. The small barnyard area has goats, pigs, cows, and other livestock; the bioparco is also home to a rare Kleinmann’s tortoise, rescued from a smuggler's suitcase in 2005. The Bioparco is one of the most popular sights in the sprawling Villa Borghese park, and you can visit as part of a Villa Borghese bike or Segway tour that also includes the Galleria Borghese, the Silvano Toti Globe Theatre, and the Pincio Gardens.
