Consult a travel agent in Singapore
Before finalizing your plan to visit Kalimantan from Singapore, it is highly recommended that you consult a couple of professional travel agents and see what they have to offer. A travel agent would be in the best position to guide you as to what suits you the most, taking a direct flight to Kalimantan or going via another airport in Indonesia.
Take a direct flight
Malaysia and Singapore are the only two countries which offer direct flights to Sepinggan Airport, Balikpapan. Balikpapan is one of the most important towns of Kalimantan. It will take you two hours and 12 minutes to reach the island from Singapore, if you take a direct flight.
Balikpapan airport has a regular flow of domestic and international flights. Apart from the airport in Balikpapan, some other towns of Kalimantan, Tarakan and Pontianak also have international airports, with flights coming from Singapore.
Take a connecting flight

From there, you can either take a flight to any of the destinations in Kalimantan or may travel to the island by road and then through a ship.
Travel by sea
If you have enough time and want to save some money, you can opt to travel to Kalimantan from Singapore by sea. Travelling by sea can be an extremely relaxing experience if you can book a ticket on a luxurious cruise.
