Banjarmasin is served by the Syamsudin Noor Airport, located about 25 km outside the town. The town is served by a deepwater port, Trisakti Harbour, which is the centre of the Barito basin; exports include rubber, pepper, timber, petroleum, coal, gold, and diamonds. Passenger ships and ferries to and from Java also carry their operation here.
The city is laced with flood-prone waterways, and many houses are built on rafts or stilts over the water. The waterways are also used for travel, using relatively small rowboats (only major rivers are accessible by larger speedboats, tugboats, longboats, and barges).
