Lima's public transport is not extensive compared to other Latin American megacities. Lima's public transport network consists of the following:
Tren Electrico ( Metro)
Metropolitano ( A bus rapid transit system)
Combis and Micros ( Privately owned minibusses)
The metro and Metropolitano are the most organized and the easiest to use for tourists. They aren't cramped like the city's micros and com is and don't stuck in traffic
How to Use Lima Metro
Lima metro is a relatively new metro system and is yet to be expansive. Currently, Lima has only one metro line running from the south of the city to the northeastern part of Lima.
The metro also passes through the touristic districts of Miraflores, San Isidro, and central Lima.
The metro stations are quite basic. They all have a couple of ticket offices, ticket recharge machines, basic maps, and turnstiles where you tap your Tarjeta ( Lima transport electronic card). A single metro ticket costs 1.5 soles.
The metro operates from 6.00 am to 10.00 pm. Trains arrive after every 6-10 minutes
How to Use a Tarjeta intelligente.
Tarjeta cards cost 5 soles and are bought at any vending machine at the metro stations or at Metropolitano stations. You can use them to pay for either the metro or Metropolitano.
Make sure you just have the money needed to pay for the card and load fare, the machines don't give change.
How to Use Lima's Metropolitano
The Metropolitano is more extensive compared to the metro. It connects Chorillos in the south of Lima to Comas in the north via Barranco, Miraflores, San Isidro, and the city center.
Payment is only using tarjeta cards. A single Metropolitano trip costs 1.5 soles. Metropolitano buses run from 5.30 am to 11.00 pm at an interval of about 5 minutes. You have to wait longer (about 10-15 minutes) during peak hours since buses are packed.
Taxi regulation in Lima isn't strict. unregistered taxis are the majority in the city compared to official registered taxis. While there's no problem taking an unregistered taxi during the day, taking these taxis at night poses a security threat since you can't track them down in case of any incident.
There are 3 categories of taxis in Lima
Independent taxis ( Taxi independente)
Radio taxis (Taxi estación)
Independent taxis are painted yellow and are registered with the municipal council. These taxis have a sticker indicated SETAME that has the vehicle's registration on their windows. These taxis pick and drop off passengers anywhere.
Radio taxis are only available on request ( think of Uber) and are all painted white with the company name indicated. Uber is illegal in Peru, though it still operates irregularly in Lima and is cheaper compared to other taxis. Common taxi apps in Lima are Easy taxi and taxi green.
Taxi Remisse are luxury taxis, they aren't paints in any particular color and don't have any signs. These are available on request from various taxi companies in Lima.
Taxis in Lima are not metered. Fare is decided by negotiations between the driver and passenger.
Buses in Lima
Using micros and combis is chaotic. They don't follow specific routes and there are no designated bus stops and terminals. You can find buses to all parts of the city at Av. Arequipa and Av. Wilson in central Lima. The destinations are indicated on the windscreen.
I wouldn't recommend taking buses if you're new in Lima. Most locals don't understand the bus system fully, it's even more hectic for nonlocals.
