We did a 2 nights, three days tour with Dennis in October 2021 and loved it ! We were a group of 7 and took a house boat. To be on the boat day and night and to observe Mahakam River life from the boat was a unique experience. We also loved the floating village Muara Enggaram. It was stunning to see the village life literally on the water. The food was excellent, a lot of vegetarian options and the boat was very clean. We even saw a freshwater dolphin, a long nose monkey and many other monkeys 🙂 Dennis took good care of everything and is able togive many information in English
