Tourism industry in Indonesia is just rising to the another level, not only Bali and Yogyakarta as culture tourism, Lombok and Raja Ampat as natural tourism industry, but there are many potential regions in Indonesia. I won't say that South Borneo is the only potential one.
What does South Borneo have in tourism industry? The culture and nature. On the culture, South Borneo has Banjar culture and Dayak culture which regardes as native cultures in Borneo land. But are same same root, but they are different in many aspects on social living. Banjar people (Banjarese) mostly live in the city while most of Dayak people live in the forest of South borneo.
On the nature, this region has different interesting nature places that many people dont know. Here, i made a list about the places in South Borneo.
Martapura River Waterfront
Sabilal Muhtadin Mosque
Sultan Suriansyah Mosque and Tomb
Pasar Terapung Kuin
Pasar Terapung Lok Baintan
Diamond Traditional Mining Cempaka
Lambung Mangkurat Museum
Riam Kanan Reservoirs
Cahaya Bumi Selamat Diamond Market
Traditional House Teluk Selong
- Tanah Laut
Batu Hapu Cave
Loksado Forest Trekking
- Kota Baru
Most of those places even aren't unpopular by Banjarese themselves, its because tourism industry is not the one of biggest industry here. The government tends to be more welcome to the investors who want to exploit coal mining and palm oil plantation.
