Can I travel from Bali (Denpasar) to Balikpapan in Kalimantan, Borneo, Indonesia? Or do I need to fly?
please allow me to help for an answer.
Since Denpasar (Bali Island) and Balikpapan (Borneo Island) was located in a different island and were separated by the sea which wider than between Bali Island and Java Island (which from bali to java, we can travel by bus), there is not possible for you to travel from Denpasar to Balikpapan not by the plane. There are several air service from Denpasar to Balikpapan.
Hope my answer can help you a little bit..
