In Monterrey you can find two interesting Zoo. One is in the City, named Parque La Pastora.
The other named Bioparque Estrella is outside the city, but it have a lot of animals out of gates.
In Bioparque Estrella you take like a bus and the bus rides you all around the park to let you see the differents animals running over there!!!!
Some times the animals walk to the bus so you can touch and feed them
Bioparque - it is about 1 hour from the middle of Monterrey. It is a wildlife preserve dressed up as the African Savannah. They imported African dirt to make the animals feel at home!!!
