Why it matters: Visitors can take a smooth ride in the gondola from one end of the zoo to the other and enjoy a unique view of the city skyline, Balboa Park landmarks and animal habitats.
It's also an efficient and fun way to navigate the 100-acre wildlife park, especially for tired legs.
Flashback: The Skyfari aerial tram opened in 1969, when zoo admission was $1.50 and memberships were $12.50. That's about $13 and $110 in today's dollars.
If you go: The tram is open from 10am to close, and would be beautiful during golden hour or sunset.
Pro tips: Many animals, like the big cats and giraffes, are most active in the mornings, so get to the Zoo or Safari Park early to beat the crowds and see the most wildlife.
