The San Francisco Zoo has free admission for the first Wednesday of every month. However, you should be ready to go on that day of free admission because the zoo will be packed with people! Parents like to bring their kids with them. You will see many animals. Don't miss those cute koala bears or those sea otters! Beware of the lions! If you are hungry, you can stop by the leaping lemur cafe. The food is a bit pricey, but the pizza is delicious. If you plan to go to the zoo, don't forget to visit the petting zoo!
