We will start our adventure expedition after breakfast at hotel in Putussibau and head towards the headwaters of the Kapuas by long boat. The long boat is about 1 ½ – 2 meters wide and 6 – 8 meters long with capacity for 4 – 5 passengers. The long boat has no roof so it will be hot and also little noisy. It is recommended to wear your water sport sandals (TeVa) or rubber shoes and bring ear plugs, hat, long sleeve, short pants, extra snacks & drinks and dry bags.

This journey will be undertaken with our porters as well as our guide. On the way the boat will be stop for a toilet break, cleaning the propeller, refill gasoline or to fix the engine, if required! We will pass some Dayak Villages on the riverside and their unique daily river life as well as some birds such as Eagle, King Fisher, Long Tailed Parakeet.

Day 5: Kapuas river – Bungan river (B,L,D)

After breakfast, we continue our journey by long boats as far as up stream as possible. On the way we may stop at the Dayak village to see local communities and long houses. We will also pass some rapids, slash and burn agriculture (shifting cultivation) as well as the local people looking for gold, some by traditional methods and some by machine along the river side. In certain places we have to push the boat as the level of the water in the dry season may be too shallow.

Here you will experience how amazing the boatmen are and what we call “the Stone Men: the boat crew who know exactly where the rocks are and how to get away from the rapids. It’s a great ‘adventure challenge’ that you will experience. If the rapids are too challenging we have to walk along the rocks on the river side and the boat will pick us up. It’s tough here!

Lunch on the way. Dinner and overnight at the river side with tents or temporary house or local house.

Day 6: Bungan River – Tanjung Lokang (B,L,D)

Continue our journey after breakfast. It’s more and more challenging here with the rapids. Go down some rapids with the boat and in other areas we push the boat, walk on the rocks but overall we “enjoy” the challenging experience of the rapids. On the way we will see the tropical rainforest of Kalimantan, shifting cultivation, traditional gold mining in the river, temporary huts, till we reach Tanjung Lokan. Tanjung Lokan are small villages located inside Betung Kerihun National Park. If you are a handy craft collector you may find some nice baskets, “Mandau” traditional machete, “Sumpit” blow gun, or “Tangguy” traditional farmer hats etc. You will enjoy lunch on the way.

Dinner and overnight at a local house.

Note: The duration of the long boat journey is depend on what happened on the river. Normally the journey starts after breakfast and runs until in the mid-day for lunch. Then the long boat will start again but will stop before dark to set up the camp to prepare meals. Sometimes we have to continue the journey longer to catch the best places to stay overnight. Here we need your flexibility so you will make the most of your journey.
