The public transport system in Siborongborong is straightforward, informal, and entirely road-based. Unlike large metropolises, this highland town does not have a metro, tram, or train network within the city limits. Instead, locals and visitors rely on a mix of motorized rickshaws, public minivans, and shared taxis to navigate the area. The system is designed to serve the practical needs of the community, making it an authentic, albeit rustic, experience for travelers.
The most iconic and ubiquitous mode of transport you will encounter is the becak bermotor (motorized rickshaw), often referred to locally as a bentor. These consist of a motorcycle attached to a sidecar, often painted in bright colors. They are the primary way to get around the town center and residential areas for short distances. Becaks are convenient because they can navigate narrow lanes and offer a door-to-door service that larger vehicles cannot match. They are easy to find; you will see them parked at street corners or cruising slowly looking for passengers.
For moving along the main roads or traveling between districts, the angkot (public minivan) is the standard option. These are modified passenger vans that follow specific routes, although in a smaller town like Siborongborong, the routes are often just linear along the main highway (Jalan Sisingamangaraja). They do not have fixed stops; you simply wave your hand to hail one from the roadside and tell the driver to stop when you are close to your destination. They are the most budget-friendly way to travel but can be cramped and do not run on a strict timetable.
The payment system across all forms of local public transport is strictly cash. There are no travel cards, electronic passes, or tap-to-pay systems available here. You must pay the driver directly in Indonesian Rupiah (IDR). For an angkot ride, the fare is fixed and very low, usually a few thousand rupiahs. For a becak, the price is not fixed and must be negotiated before you hop in. It is highly advisable to carry small denominations (notes of 2,000, 5,000, and 10,000 IDR), as drivers often struggle to provide change for large bills.
Ride-hailing apps like Grab or Gojek have a presence in the region, but availability can be inconsistent compared to major cities. You might find drivers for motorcycle taxis (ojek online) or cars during the day, but wait times can be longer, and service may be non-existent late at night or in remote outskirts. It is best not to rely solely on apps for time-sensitive trips, such as catching a flight, unless you book well in advance.
For tourists planning to explore the surrounding highlands or visit Lake Toba, car rental with a driver is the most popular and practical alternative. While not "public transport" in the traditional sense, it is the standard way for visitors to move around due to the freedom it offers. You can arrange this through your hotel or at the airport. Additionally, for intercity travel, shared taxis known locally as "Travel" (usually Toyota Innova or Avanza cars) are very common. They operate from small offices or terminals in town and connect Siborongborong to other major hubs.
A special feature of the local transport landscape is the DAMRI bus service connected to the nearby Sisingamangaraja XII Airport. These government-operated buses provide a reliable and affordable link between the airport, Siborongborong, and the tourist area of Parapat on Lake Toba. They are modern, air-conditioned, and run on a schedule aligned with flight arrivals, making them one of the few scheduled transport options in the area.
Operating hours for local transport are generally limited to daylight hours and early evening. Angkots and becaks are plentiful from early morning until around 6:00 PM or 7:00 PM. After dark, the frequency drops significantly, and by late night, it can be very difficult to find public transport on the street. If you plan to be out late, ensure you have a phone number for a local driver or arrange a pickup with your accommodation beforehand.
