The public transport system in Ushuaia is relatively small but efficient, designed to serve the needs of both residents and the many visitors who arrive throughout the year. Due to the city's compact size and challenging terrain, there is no metro, tram, or trolleybus network. Instead, the primary mode of public transit consists of a local bus service that connects the downtown area with outlying neighborhoods and key points of interest.
The local buses, known as colectivos, are operated by the municipal company UISE. There are only a few lines (typically identified by letters like A, B, and C), making the system easy to understand even for first-time visitors. These buses are modern, heated—a crucial feature given the local climate—and generally run from early morning until around midnight. While they are perfect for moving within the city limits, they do not extend to the more distant tourist attractions like the ski centers or the heart of the national park.
To use the bus system, you must have a SUBE card, the same magnetic contactless card used in Buenos Aires and across Argentina. Buses do not accept cash, and drivers cannot sell tickets. You can purchase and load credit onto a SUBE card at "kioscos" (convenience stores), pharmacies, or lottery shops displaying the SUBE logo. If you have already traveled elsewhere in the country, your existing card will work here as well. The fare is affordable, making it a budget-friendly option for getting around.
For many tourists, taxis and remises are the most practical alternatives. Taxis are easily recognized by their white color with yellow roofs and can be hailed on the street or found at designated ranks. Remises look like private cars and must be booked by phone or at an agency office; they operate with fixed rates or meters similar to taxis. Both are reliable, safe, and widely used, especially for returning to hotels after dinner or carrying luggage to the port.
Since the standard public buses do not cover the entire region, travelers heading to major attractions such as Tierra del Fuego National Park or the Cerro Castor ski resort typically rely on minibuses or shuttles (often called combis). These depart regularly from a designated terminal near the waterfront and port area. They offer a convenient bridge between public transit and private tours, allowing you to reach trailheads and scenic spots without renting a car.
A unique feature of the local transport landscape is the End of the World Train (Tren del Fin del Mundo). While it is a historic steam railway rather than a mode of urban commuting, it is a functional part of the tourist infrastructure. It transports visitors on the final leg of the journey into the national park, following the original route used by prisoners in the early 20th century. It offers a nostalgic and scenic way to traverse the valley, complete with heated carriages and audioguides.
For those who prefer total independence, car rentals are available and popular for exploring the surrounding lakes and mountains at your own pace. Bike rentals are also an option, though they are primarily used for recreational riding rather than commuting, given the steep streets and unpredictable winds. Walking remains the best way to explore the city center, which is concentrated around the flat waterfront and the main commercial street, San Martín Avenue.
