By taxi
People also rely on a network of collective taxis. As a tourist, you should ask the driver if he is going by your destination. Prices vary by distance but a 10-15 minute ride should be around 20 pesos in a yellow taxi and 40 pesos in a white taxi.
Taxis are collective but in no way have pre-established routes. You tell the driver where you want to go and if the taxi is empty he should take you and if during the way to your destination someone else happens to go somewhere close to where you are going he will hop in the taxi and continue. It is advisable then to always try and sit in the front seat. About prices, anywhere in the city is 20 pesos in a yellow taxi, 40 pesos in a white taxi. It doesn't matter where in the city you are going. Many Taxis will stop even if they have a passenger, and ask you where you are going. If you are headed in the same direction or near the same direction as the original passenger, he will take you as well. You do not get a discount if he has a passenger, the price is the same.
