Denver public transport: tickets, passes and apps

Denver's transit is run by RTD, and the ticketing is simple enough that you rarely need to think about it. A single local fare covers one ride on light rail or bus within the local zone. A local day pass costs roughly the price of two singles and is the right buy when you plan three or more rides in a day: downtown to a museum, back to the hotel, out again for dinner.

If you are in Denver for a weekend of sightseeing, buy a day pass each morning you will move around and pay per ride on the days you stay in one neighbourhood. If you are here for a week and riding daily, check the weekly and monthly pass prices in the RTD app before you commit; they only pay off with consistent use.

The airport is the exception. The A Line commuter rail from Denver International Airport to Union Station sits in a higher fare zone, so a local day pass does not cover it. Buy the airport fare for that leg, then switch to local tickets once you are in the city.

At light rail and commuter rail stations, tap a contactless credit or debit card, a phone wallet, or an RTD-issued card at the gate reader. The same tap can be used to buy a day pass if the system recognises repeat taps; check the current rules on the reader screen before relying on it.

On buses, you can pay cash with exact change or tap a card where readers are fitted. Drivers generally do not give change, so keep small notes. The RTD app lets you buy and store tickets on your phone, which is the easiest option if you are buying passes for several days.

If you are arriving at the airport and heading straight downtown, buy the airport fare at the station before boarding the A Line. Ticket checks are common on the commuter rail, and a fare-evasion citation is expensive.

RTD's fare structure is zone-based rather than distance-based. Local fares cover travel within the core area, which includes downtown Denver, most of the light rail network and the inner suburbs. Regional fares apply to longer trips out to places like Boulder or the airport corridor.

For a typical visitor staying downtown or in LoDo, almost everything you want is in the local zone: Union Station, the Convention Center, the stadium district, the art museum and the 16th Street Mall. You only need to think about zones if you are heading to the airport, Boulder or a far suburb.

The free MallRide shuttle runs along 16th Street and is the one service you never pay for. It is useful for the short hop between Union Station and the Civic Center area.

Denver International Airport (DEN) is about 40 km east of downtown, and the A Line commuter rail is the standard car-free option. It runs from the airport to Union Station in roughly 35–40 minutes, with a handful of stops on the way. Buy the airport fare at the airport station before boarding.

From Union Station you can walk or take the free MallRide into downtown, or connect to light rail and buses with a local ticket. If your hotel is outside the core, check whether a bus or a short ride-hail from Union Station is faster than a rail connection.

A taxi or ride-hail from the airport to downtown typically costs far more than the train and takes longer in peak traffic. For a group of three or four with luggage, a ride-hail can still make sense; for one or two travellers, the train is almost always the better deal.

Denver's light rail is useful for the downtown core and a few inner suburbs, but it does not cover the whole city. For destinations like the Denver Zoo, some museum campuses or the western suburbs, check whether a bus connection is practical or whether a ride-hail is faster.

Buy your ticket before you board. On rail, gates and ticket machines are at the station; on buses, pay the driver. Keep your ticket or phone screen available until you leave the system, since inspectors can ask to see it.

If you are planning a car-free day, group your stops along one rail line rather than zig-zagging across the city. Denver's grid is easy to walk in the centre, and the free MallRide covers the main downtown spine.
