History & Background

Kalimantan, the Indonesian portion of the island of Borneo, boasts a rich and complex history deeply intertwined with its abundant nature. Since prehistoric times, the island has been inhabited by various ethnic groups, including the Dayak people, who share a profound spiritual connection with the forest. The forests of Kalimantan, particularly in the Central Kalimantan region, have long been vital natural resources, providing timber, non-timber forest products, and extraordinary biodiversity. However, the island's modern history is also marked by significant challenges. Widespread deforestation due to oil palm plantation expansion, illegal logging, and mining has threatened the survival of the fragile tropical rainforest ecosystem and, most importantly, the orangutan habitat.

The Bornean orangutan (Pongo pygmaeus), like its Sumatran cousin, faces serious extinction threats, largely due to habitat loss. Conservation efforts have become paramount, and Central Kalimantan has become a hub for numerous organizations dedicated to protecting orangutans and their forests. Tanjung Puting National Park, which will be the primary focus of our journey, is a prime example of these conservation endeavors. Established in 1980, the park initially served as a wildlife reserve aimed at protecting orangutan populations and other wildlife. Over time, its status was elevated to a national park, recognizing its broader ecological significance.

The history behind the establishment of orangutan rehabilitation centers in this area is also noteworthy. Organizations like the Orangutan Foundation and the Borneo Orangutan Survival Foundation (BOSF) have played a crucial role in rescuing orangutans saved from illegal trade, orphaned, or injured, and rehabilitating them for reintroduction into the wild. Camp Leakey, a historic research and reintroduction facility founded in 1971 by Dr. Biruté Galdikas, a renowned Canadian anthropologist, is one of the most iconic locations within Tanjung Puting. The long history of research and conservation here has provided invaluable insights into orangutan biology and behavior, and has inspired global conservation efforts. This 5-day journey offers not just a chance to see orangutans, but also to understand the struggles and successes of conservation in one of the world's most critical forests.

Main Attractions

This 5-day adventure into the interior of Central Kalimantan offers an extraordinary blend of natural beauty, stunning wildlife, and profound cultural experiences. The primary focus of this trip is Tanjung Puting National Park, an ecological gem in the heart of Borneo renowned globally for its significant orangutan population and its tenacious conservation efforts.

1. Witnessing Orangutans in Their Natural Habitat and Rehabilitation Centers:

Camp Leakey: This is the heart of your orangutan exploration. Founded by Dr. Biruté Galdikas, Camp Leakey is a historic orangutan research and reintroduction center. Here, you will have the incredible opportunity to witness rehabilitated orangutans returning to the wild during the afternoon feeding sessions. This is not a zoo; it's an ecosystem where rescued or orphaned orangutans are given a second chance at an independent life in the forest. Watch them descend from the trees, interact with each other, and take the offered fruits. This experience is both moving and educational, providing deep insights into the intelligence and vulnerability of these primates.
Pondok Tanggui & Pasir Panjang (Feeding Stations): In addition to Camp Leakey, there are other feeding stations like Pondok Tanggui and Pasir Panjang. Pondok Tanggui typically has a morning feeding session, while Pasir Panjang offers a more relaxed orangutan viewing experience. Visits to these stations allow you to see orangutans at various stages of rehabilitation and from different family groups.
Encounters with Wild Orangutans: As you cruise along the Sekonyer River, be prepared for surprises! Wild orangutans are often spotted swinging through the trees along the riverbanks. These are magical moments that remind you that you are truly in the wild.

2. The Iconic Sekonyer River Journey:

Houseboat (Klotok): The core experience of this trip involves exploring the river aboard a traditional houseboat, known locally as a 'klotok'. This klotok will be your floating home for several days, taking you deep into the jungle. The screens on the klotok allow you to sleep under the stars, surrounded by the soothing sounds of the forest. This river journey provides access to otherwise hard-to-reach areas and offers a unique perspective on the riverine ecosystem.
River Life: Throughout your journey, you'll witness the daily life unfolding along the riverbanks, from small villages to fishermen at work. The Sekonyer River itself is a lifeline, providing water and a vital transportation route.

3. Other Biodiversity Highlights:

Proboscis Monkeys: A distinctive feature of Borneo, the proboscis monkey with its uniquely large nose, is often seen along the riverbanks, especially in areas with mangrove and nipa palm vegetation. Watch them hang from branches or leap into the water.
Exotic Birds: Tanjung Puting National Park is a birdwatcher's paradise. You can spot various bird species, including hornbills, different types of kingfishers, tailorbirds, and many more. Their calls will be the soundtrack to your journey.
Other Wildlife: Depending on your luck, you might also see monitor lizards, long-tailed macaques, snakes, and even estuarine crocodiles in their natural habitat.

4. Local Cultural Experience:

Tanjung Puting Village: Visits to small villages along the river offer insights into the lives of the Dayak and Bugis communities who reside there. You'll observe traditional stilt houses, children playing by the river, and experience the warmth of local hospitality.
Interaction with Local Guides: Your guides, often from the local communities, will share their deep knowledge of the forest, wildlife, and local culture, enriching your experience.

This 5-day itinerary is meticulously designed to maximize your chances of seeing orangutans, enjoying the natural splendor of Kalimantan, and gaining a better understanding of wildlife conservation. Every moment here is an opportunity to reconnect with nature and witness the wonders of Borneo.

Travel Tips & Logistics

Planning a trip to the interior of Central Kalimantan, especially for an orangutan and river adventure, requires thorough preparation. Here's a guide to logistics and essential tips to ensure your experience is smooth and enjoyable:

1. Getting to Central Kalimantan:

Flights: The most common starting point for this adventure is Pangkalan Bun (Iskandar Airport - PKN) in Central Kalimantan. You can fly to Pangkalan Bun from major Indonesian cities like Jakarta (CGK), Surabaya (SUB), or Semarang (SRG). Airlines such as Garuda Indonesia, Lion Air, and Citilink typically serve these routes. Ensure you book your tickets well in advance, especially if traveling during peak season.
From Pangkalan Bun to the National Park Gateway: Upon arrival in Pangkalan Bun, you will be met by your tour operator and taken to the port in Kumai, which is the main gateway to Tanjung Puting National Park.

2. Accommodation & Transportation within the National Park:

Houseboat (Klotok): This is your primary accommodation within the national park. Klotoks vary in size, from small ones for couples to larger ones for groups. They typically feature simple sleeping quarters (often with mattresses on an open upper deck or small enclosed rooms), a toilet, and a dining area. A guide and cook will accompany you, preparing meals and navigating the river.
Other Options (Limited): There are a few basic guesthouses along the river or near research posts, but the klotok experience is highly recommended for a true adventure.

With proper planning, your 5-day adventure in the interior of Central Kalimantan will be an extraordinary and meaningful experience.

Cuisine & Local Experience

A journey into the interior of Central Kalimantan is not just about orangutans and forests; it's also about experiencing authentic flavors and the warmth of local culture. While the culinary experience within the jungle is often simple yet fresh, it offers a glimpse into the lives of communities dependent on the surrounding natural resources.

Cuisine on the Klotok:

One of the most delightful aspects of staying on a houseboat (klotok) is the food served. Experienced local cooks will prepare delicious meals using fresh ingredients often sourced from local markets in Pangkalan Bun or Kumai, and sometimes even from catches in the river or local gardens.

These typically include white rice as the staple, various side dishes like fried or grilled fish (often fresh river fish), chicken or beef cooked in rich Indonesian spices (such as rendang or semur), and stir-fried fresh vegetables.
Fresh River Fish: Given you are along the river, river fish are a highlight. Enjoy catfish, baung, or pangasius cooked fried crispy, grilled with spices, or in a light clear soup.
Local Vegetables: Stir-fried vegetables like water spinach (kangkung), bok choy, or eggplant are common. Sometimes, you'll also find dishes using young leaf shoots found only in the jungle.
Tropical Fruits: At the end of each meal, you'll be served a variety of seasonal tropical fruits such as papaya, banana, oranges, or mangoes. They are sweet and refreshing, perfect to end a meal.
Beverages: Plain water, tea, and coffee are usually available throughout the day. Kalimantan coffee has a distinct and strong flavor.

Local Experiences Along the River:

Beyond the cuisine on the klotok, interacting with local communities along the Sekonyer River provides valuable cultural experiences.

Visiting Villages: When stopping at villages like Tanjung Puting Village, you'll observe how the Dayak and Bugis people live their lives. Traditional stilt houses built on wooden poles are characteristic, designed to protect against floods and wild animals.
Local Hospitality: The villagers are generally very friendly and often enthusiastic to welcome visitors. Children will usually wave cheerfully as your klotok passes by. If you have the chance for closer interaction, they will happily share stories about their daily lives.
Simple Handicrafts: In some villages, you might find opportunities to see or purchase simple handicrafts made by the locals, such as woven items or small wood carvings. These can make unique souvenirs that support the local economy.
Learning from Local Guides: Your guides, often from the local community, are invaluable sources of knowledge. They are not only experts in navigating the jungle and spotting wildlife but can also tell you about local traditions, beliefs, and ways of life.
Listening to the Night Sounds: The evenings on the klotok are a unique experience. The sounds of insects, frogs, and mysterious calls from within the forest create a soothing natural symphony. Sometimes, you can also hear the distant sounds of village life.

These culinary and local interaction experiences complement the orangutan and river adventure, providing a more complete picture of the beauty and richness of Central Kalimantan. It's an opportunity to connect with nature and humanity in harmony.
