South Kalimantan: the province of rivers and floating markets

South Kalimantan is the smallest province on Borneo by area and one of the most densely settled, with a culture built on rivers rather than roads. Banjarmasin sits at the meeting of the Martapura and Barito, and until recently most goods arrived by boat. The floating markets at Lok Baintan and Kuin still open before sunrise, when women paddle jukung loaded with fruit, vegetables and hot food.

Beyond the city the province changes quickly. The Meratus mountains rise to the east, home to the Dayak Meratus and to Loksado, where bamboo rafts run down clear rivers through forest. Banjarbaru, the administrative capital, has the airport and a grid of tree-lined streets, while Martapura is the centre of the diamond trade and of Banjarese Islamic scholarship.

Where South Kalimantan fits in a Borneo trip

South Kalimantan is the most accessible province in Kalimantan for a short trip. Banjarbaru's Syamsudin Noor airport (BDJ) has frequent flights from Jakarta, Surabaya, Yogyakarta and Denpasar, and the city is close enough to Banjarmasin for a morning arrival and an afternoon on the river. That makes it a realistic two- or three-day stop rather than a full expedition.

It also works as a gateway to the rest of Borneo. Roads run north to Palangka Raya and east toward the Meratus and the border with East Kalimantan, and the Barito river connects the interior to the Java Sea. Travellers crossing the island often pass through Banjarmasin without stopping, which is a mistake: the food alone justifies a night.

The province pairs well with Central Kalimantan. A week that combines the floating markets and Loksado with Tanjung Puting, reached via Pangkalan Bun or Palangka Raya, gives a rounded picture of southern Borneo without repeating the same landscape twice.

Banjarmasin, the floating market and the rivers

The classic Banjarmasin morning starts at 05:00, when a klotok leaves the city piers for Lok Baintan. The market forms on the water around dawn: dozens of jukung, each paddled by a woman in a wide-brimmed hat, trading bananas, chillies, cakes and river fish. It is a working market, not a show, and the best photographs come from asking permission and then putting the camera down.

Back in the city, the waterfront along the Martapura is a tangle of stilt houses, mosques and floating shops. The Sultan Suriansyah mosque, one of the oldest in Kalimantan, sits near the river mouth, and the Menara Pandang tower gives a view over the whole basin. In the evening, the riverside food stalls serve the province's signature dishes.

Kuin market, closer to the centre, runs a smaller floating market on other mornings and is easier to reach if you do not want a pre-dawn boat. Both markets are affected by river levels and holidays, so ask locally the day before rather than relying on a guidebook schedule.

Getting there and moving around

Syamsudin Noor airport sits between Banjarbaru and Banjarmasin, about forty minutes from the city centre by road. Taxis and ride-hailing apps are reliable, and the airport has a bus link to both cities. There is no useful train service in the province, so road transport is the default.

Within Banjarmasin, angkot minibuses and ride-hailing motorcycles cover most of the city, but traffic is heavy and journeys are slow. For the floating markets, book a boat through your hotel or at the pier; prices are negotiable and should be agreed in writing, including the departure time and the number of stops.

For Loksado and the Meratus, take a car with a driver from Banjarmasin or Kandangan. The road climbs through rubber and rice country before reaching the hills, and the final stretch to the rafting start point is narrow but paved. Shared transport exists but is slow and infrequent.

• Loksado: bamboo rafting, Meratus foothills

Loksado and the Meratus mountains

Loksado is a small town in Hulu Sungai Selatan where the Amandit river runs clear over stones. Bamboo rafting here is the province's best-known outdoor activity: two or three people sit on a lashed bamboo platform while a guide poles downstream through rapids and forest. Trips last two to four hours and finish in villages where you can eat and stay.

The surrounding hills are home to Dayak Meratus communities, whose longhouses, swidden farms and customary rules differ from the riverine Banjarese culture of the lowlands. A guide is essential for visiting villages respectfully, and homestays are basic but welcoming. The cool altitude makes Loksado a pleasant escape from the coastal heat.

Nearby, the town of Kandangan is famous for ketupat kandangan, a dish of rice cakes in coconut fish broth that is worth planning a meal around. Negara and Barabai are also useful stops if you are travelling overland toward the east.

When to go and what to eat

The dry season, June to September, is the best time for the floating markets and for rafting, when the river is low and clear. The wet season brings higher water, more dramatic scenery and occasional flooding in Banjarmasin, where parts of the city sit below river level.

Banjarese food is one of the reasons to come. Soto banjar is a fragrant chicken soup with rice cakes; ketupat kandangan pairs rice cakes with a coconut fish broth; and the grilled fish and prawns along the river are excellent. The province is also known for its sweet drinks, including es kelapa and the vivid pink es campur.

Ramadan changes the rhythm of the city: the floating market runs earlier, many restaurants close during the day, and the evening food streets become the main event. Travellers are welcome but should dress conservatively and avoid eating in public during daylight hours.

Costs, beds and local etiquette

Banjarmasin has the widest range of hotels in the province, from IDR 200,000 guesthouses to four-star properties around IDR 800,000. Banjarbaru is quieter and better value, while Loksado offers simple homestays from IDR 150,000 with meals arranged separately.

The province is conservative and predominantly Muslim. Dress modestly away from the riverfront, ask before entering mosques, and use your right hand for greetings and payments. The floating markets are workplaces, so avoid blocking a jukung's path for a photograph and buy something from the traders you photograph.

Cash is essential in the markets and the hills. Bring small notes, since change is scarce, and expect limited ATMs outside the cities. Tipping is not standard, but a small tip for boatmen and guides is a welcome gesture.

Questions people actually ask

What time does the floating market start?

Boats leave Banjarmasin around 05:00 and the market is busiest between 06:00 and 07:30. It winds down by mid-morning, so a late start means missing most of the trading.

Can I visit Loksado as a day trip?

It is possible but rushed. The drive from Banjarmasin takes about three hours each way, so staying one night in Loksado or Kandangan gives time for rafting and a village walk.

Is Banjarmasin safe for solo travellers?

Yes, with ordinary precautions. Petty theft is uncommon, but traffic is chaotic and river currents are strong. Use licensed boats, keep valuables out of sight, and avoid walking alone in unfamiliar areas after dark.

What is the best local dish to try first?

Soto banjar, a chicken soup with rice cakes, is the standard introduction. Ketupat kandangan and grilled river fish are the other essentials, and the riverside warungs are the most atmospheric places to eat them.
