SAN FRANCISCO, CALIFORNIA – Muni trains can feel confusing the first time you ride them in San Francisco. They run underground like a subway downtown, pop up onto city streets in the neighborhoods, share some stations with BART, and use line letters instead of train names.
I find that many locals feel totally comfortable taking BART into the city. But they balk at the idea of riding MUNI once there–or just have never thought about it.
I ride MUNI every week. Especially on modern lines like the T Line, it’s a super cheap, easy, safe way to get around.
Here’s the practical beginner’s guide. Let’s start with a video I made showing the exact process:
First, Know What “Muni Trains” Means
When people say “Muni trains,” they usually mean Muni Metro, San Francisco’s light rail system. The current Muni Metro lines are:
- J Church
- K Ingleside
- L Taraval
- M Ocean View
- N Judah
- T Third
SFMTA says Muni Metro is the third-busiest light rail system in the United States, with 151 light rail vehicles and average weekday ridership of 173,500 passengers as of 2024.
The trains work a little differently depending on where you board. Downtown, they operate in subway stations, sharing space with BART. You can ride BART to the city, go up an escalator, go down some stairs to MUNI, and transfer to a MUNI train without ever going above ground.
In many neighborhoods, they operate at street-level stops or raised boarding islands. SFMTA says all subway stations and on-street Muni Metro stations are wheelchair accessible, and many street-level stops also have accessible boarding platforms.
Step 1: Figure Out Your Line
The simplest way to ride Muni is to use the SFMTA Trip Planner, Google Maps, Apple Maps, the Transit app, or another real-time transit app. SFMTA also offers a Muni Metro map and NextMuni real-time arrival information by route or stop.
As a quick mental map:
N Judah is useful for the Inner Sunset, UCSF, Golden Gate Park access, and Ocean Beach.
T Third connects Chinatown, Union Square/Market Street, Yerba Buena/Moscone, Mission Bay, Chase Center, Dogpatch, Bayview, and Sunnydale. The Central Subway extended the T Third through SoMa, Union Square and Chinatown, with three underground stations and one surface station.
You can transfer to this one from Powell BART. It’s the line I use the most!
J Church runs through neighborhoods including Noe Valley and Church Street.
K Ingleside and M Ocean View serve the southwest side of the city, including West Portal, Balboa Park connections and areas near San Francisco State.
L Taraval serves the Parkside and Outer Sunset area.
The F line, which runs through the Embarcadero, is technically a cable car instead of light rail, but I count it as a train. It’s very cool as it uses restored, historic cars!
Step 2: Pay Before or As You Board
As of May 2026, an adult Muni single ride costs $2.85 with Clipper or MuniMobile and $3.00 with cash or a Metro ticket machine. A single ride is good for 120 minutes of travel, including transfers across Muni buses and light rail.
You can pay several ways:
Clipper card or mobile Clipper: Tap at a fare gate in a subway station, or tap at the reader when boarding on the street.
Credit or debit card: SFMTA says riders can tap a credit or debit card at any door when boarding.
MuniMobile: Activate your fare before boarding. At a Muni Metro station, show the fare to the station agent or go through the appropriate gate. SFMTA says there is no need to tag the farebox when using MuniMobile.
Cash: Use exact change at the front of the train or bus and keep your transfer as proof of payment.
Ticket machine: Ticket vending machines are available in Muni Metro stations. SFMTA says riders should show the ticket to a station agent or use the appropriate gate.
One important note: keep your proof of payment. SFMTA says proof can be your ticket, pass, app, Clipper card, Clipper app or mobile wallet.
Fines can be hundreds of dollars if you deliberately don’t pay! As long as you keep your proof of payment, though, you’ll be fine.
Step 3: Make Sure You Are in the Right Station Area
This is where many first-time riders get tripped up.
Several downtown stations are shared with BART, especially along Market Street. Muni and BART are different systems, even when they are in the same station complex. If you are riding Muni Metro, look for the Muni Metro signs, platforms and fare gates.
Basically, you go up the BART escalator, exit through the BART fare gate, find a sign for MUNI, and then go through the MUNI fare gate to switch to the MUNI system.
A useful rule: do not just board the first train that arrives. Check the letter and destination.
Step 4: Boarding Works Differently Underground and on the Street
In subway stations, wait behind the platform edge, check the train letter and destination, let passengers exit, then board.
On the street, the stop may be a raised platform, a boarding island, or a simpler stop marked by signage.
SFMTA says some street-level Muni Metro stops are indicated by a boarding island that may or may not include a shelter, or by yellow-banded paint on a utility pole.
If you are paying with Clipper, MuniMobile, a transfer or another pass, SFMTA says you can board through any door. If paying cash, use the front door only.
Step 5: Hold On — Seriously
Muni trains can move through subway tunnels, traffic lights, curves, hills and street-level tracks. SFMTA reminds riders to hold onto straps or posts and stay seated when possible.
The basic etiquette is the same as other transit systems: let people off first, move away from the doors, keep bags off seats when crowded, use headphones, and leave priority seating for seniors and people with disabilities.
SFMTA specifically says smoking, eating, drinking, littering and playing audio without headphones are not allowed on Muni.
Step 7: Getting Off
In the subway, trains stop at every station.
At some street-level stops, especially outside the subway, it is a good idea to signal that you want to get off by using the stop request button or cord as your stop approaches. SFMTA tells riders to pull the cable cord or push the button when nearing their stop.
Pay attention to the announcements and onboard displays. If you are unsure, sit or stand where you can see the stop names, or track your trip on your phone.
Once you exit, you can just leave! It’s not like BART where you need to swipe your card again at the exit.
It’s a little intimidating at first, but once you get the hang of it, MUNI is a super fast, easy and very cheap system.
