Route 121 is the bus (locally called a “micro”) that links Estación Mapocho, in central Santiago, with Lo Espejo, in the south of the city. It is 17.6 km long outbound and is a Red Movilidad service, the system formerly known as Transantiago. Its main axis is Av. Club Hípico, which it covers almost from end to end, passing Fantasilandia, the Movistar Arena and Estadio Dávila. Locals search for it as “recorrido 121” or “121 recorrido”. Here you have the route by section, the timetable, the Metro connections and how to find out where the bus is.
Route 121: from Estación Mapocho to Lo Espejo
Western city centre. The 121 starts at Estación Mapocho, passes Av. Pdte. Balmaceda and the Mercado de Anticuarios and takes Av. Ricardo Cumming south, with stops at Castillo, Andes, San Pablo, Santo Domingo, Catedral, Compañía de Jesús and Agustinas. It continues along Avenida Brasil, crosses the Alameda and carries on via Almirante Latorre.
Club Hípico. From Toesca it joins Av. Club Hípico, the longest stretch of the route. It passes the Escuela de Ingeniería, Fantasilandia and the Movistar Arena, crosses Av. Gral. Rondizzoni and Av. Pedro Montt and reaches Pedro Aguirre Cerda station. It then keeps heading south through the stops at Lago Ranco, Lago Pirihueico, Lago Calafquén, Pdte. S. Allende, Angel Guarello, Avenida La Marina, Avenida Lazo, Av. Departamental and Vecinal, up to Estadio Dávila and Plaza Miguel Dávila Carson.
Lo Ovalle and Raúl Silva Henríquez. From the plaza it takes Avenida Lo Ovalle (Los Cardenales, Av. Clotario Blest), passes Maipú and Punto IV and Buenaventura, and runs along Card. Raúl Silva Henríquez past its numbered passages to Av. Eduardo Frei Montalva.
Lo Espejo. The last stretch follows Av. Edo. Frei Montalva and Av. Diagonal Las Torres, crosses Av. Américo Vespucio and continues via Central and Gabriela Mistral (9 de Enero, Pedro Prado, Balmaceda, Ortiz de Zárate) to Avenida Lo Espejo. It ends at Santa Margarita.
The return trip is not an exact mirror. It leaves from Santa Margarita and Avenida Lo Espejo, passes Juan F. González and the CESFAM Julio Acuña Pinzón and comes back via Raúl Silva Henríquez and Club Hípico. After Pedro Aguirre Cerda station it turns off via Av. Carlos Valdovinos, Bascuñán Guerrero, Centenario, Plaza Yarur, Av. Pedro Montt and Avenida Beaucheff, then heads up Avenida República, stopping at República station and the Liceo de Aplicación. It reaches Mapocho via Ricardo Cumming and San Pablo and ends next to the Mercado Central.
Route 121 timetable
According to the current DTPM operating schedule (October 2026), the 121 runs every day, but not all night:
- Monday to Friday: from 05:30, with the last departures around 24:00 and about 95 departures a day.
- Saturday: from 06:30, last departures around 24:00, about 70 departures.
- Sunday: from 05:30, last departures around 24:00, about 66 departures.
In the weekday morning peak (07:00 to 09:00), the shortest scheduled interval is 10 minutes. Off-peak and at weekends, with fewer departures, expect longer intervals. Note that on Saturday it starts an hour later than on other days.
How long the 121 takes
According to the operating schedule, a full outbound trip, from Estación Mapocho to Lo Espejo, has a scheduled time of 61 minutes for 17.6 km. This is a reference time: allow extra time in peak hours or in the rain. If you are only going from the centre to Pedro Aguirre Cerda station, the trip is much shorter.
Bus stops and Metro connections
The 121 has 56 stops outbound and 61 on the return. Almost all are street stops (paraderos), named after the nearest corner; only two are next to the Metro:
- Pedro Aguirre Cerda, on Av. Club Hípico, in both directions.
- República, only on the return to Mapocho, on Av. República.
Other landmarks on the route are the Mercado de Anticuarios, the Escuela de Ingeniería, Fantasilandia, the Movistar Arena, Estadio Dávila and, on the return, the Liceo de Aplicación and the Mercado Central.
Start of the 121 in the city centre; on the return the bus ends next to the Mercado Central.
The only Metro connection in both directions, on Av. Club Hípico.
Stop on Club Hípico, where the 121 leaves the avenue and continues via Lo Ovalle towards Lo Espejo.
How to find out where the 121 bus is
To see how long until the next 121, use the App Red (in the app stores, “Red Metropolitana de Movilidad”), which is free and has an arrival predictor for each bus stop. You can also use “¿Cuándo llega?” on red.cl. Enter the bus stop code, printed on the stop sign: it starts with P, followed by a zone letter and a number. As the outbound and return trips use different streets between Club Hípico and Av. República, make sure you are at the stop for the right direction.
Fare and tarjeta bip!
Since 22 February 2026 the adult fare on Red buses is CLP 795 at any time. Secondary and higher-education students pay CLP 260 with the TNE, primary school pupils ride free and seniors with the bip! Adulto Mayor pay CLP 390. You can pay with the tarjeta bip! (it costs CLP 1,550) or with bip!QR from the App Red and other apps.
A single payment covers up to two transfers (three legs) within 120 minutes of the first validation, as long as you do not repeat the same bus route. There is no extra charge between buses; if you transfer from the 121 to the Metro at Pedro Aguirre Cerda during peak hours, you pay the difference up to CLP 895.
Tips for travelling on the 121
- The 121 has stops named after Fantasilandia and the Movistar Arena: it is a direct option to reach both from the centre or from the south.
- If you are going from Lo Espejo to the centre, remember that the return trip goes in via Beaucheff and Av. República, not via northern Club Hípico.
- On Saturday the first departure is at 06:30, not 05:30 as on other days.
- After midnight the 121 stops running; plan your trip home in good time.
