History & Background

East Kalimantan, a province stretching across the eastern part of the island of Borneo, boasts a rich and complex history, intricately woven with its stunning natural landscapes and abundant natural resources. Since prehistoric times, this region has been inhabited by various indigenous tribes, most notably the Dayak people. The Dayak people, with their diverse subgroups such as the Dayak Kenyah, Dayak Bahau, and Dayak Tunjung, have lived in harmony with the forests and rivers for centuries, developing a profound culture, traditions, and local knowledge system about Borneo's ecosystem.

The Mahakam River, as the province's main artery, has been the lifeline and center of civilization since ancient times. Historical records indicate that early civilizations around this river flourished, supported by fertile alluvial plains and easy access via waterways. Archaeologists have discovered evidence of ancient kingdoms and maritime trading centers along the river, highlighting East Kalimantan's significant role in regional trade networks in the past. One important discovery is the Muara Kaman Inscription, dating back to the 4th century AD, indicating the existence of the oldest Hindu kingdom in Indonesia, Kutai Martadipura, centered in this region.

The arrival of Europeans in the 17th century brought significant changes. The Dutch, through the VOC trading company, began to explore and control this area, primarily for the exploitation of forest products like timber and gold. This colonial period left administrative and infrastructural imprints, but also brought social and economic impacts to the local communities. After Indonesia's independence, East Kalimantan continued to develop, with a focus on utilizing its natural resources, including coal, oil, and natural gas. However, this economic growth also presented challenges, particularly concerning environmental issues and the preservation of biodiversity.

One of the most crucial aspects of East Kalimantan's background is the presence of orangutans. These iconic species have been an integral part of Borneo's ecosystem for millions of years. Unfortunately, their habitat is increasingly threatened by deforestation due to palm oil plantations, illegal logging, and forest fires. Awareness regarding the importance of orangutan conservation and their habitat has risen significantly in recent decades, driving protection efforts through wildlife sanctuaries, rehabilitation centers, and educational programs. Understanding this history and background provides a deeper appreciation for the natural wonders you will witness during your 5-day adventure in East Kalimantan, connecting you with the ongoing cultural heritage and environmental preservation struggles.

Main Attractions

This 5-day adventure in East Kalimantan is designed to immerse you in unparalleled natural beauty and cultural richness. Our primary focus is on interacting with endemic wildlife and exploring the legendary river, offering a deep and educational experience.

1. Tanjung Puting National Park (Access Extension from East Kalimantan)

Although Tanjung Puting National Park is administratively located in Central Kalimantan, the most accessible and convenient route to see orangutans from East Kalimantan often connects through this region. Visits to orangutan rehabilitation centers such as Camp Leakey or Pondok Tanggui are major highlights. Here, you will have the opportunity to witness orangutans undergoing rehabilitation before their release back into the wild. Experienced local guides will explain the behavior, ecology, and conservation efforts for the Bornean orangutan (Pongo pygmaeus). The orangutan feeding sessions at these centers provide a unique chance to see them up close while learning about the challenges they face.

Bornean Orangutan (Pongo pygmaeus): Intelligent arboreal primates with a close kinship to humans. Their fur color varies from bright orange to dark, and adult males have distinctive cheek pads.
Conservation Efforts: Learn about programs run by organizations like the Orangutan Foundation International (OFI) to rehabilitate orphaned orangutans and reintroduce them to the forest.
Boat Journey: The trip to the rehabilitation centers is typically done by klotok (motorized boat) along the river, offering opportunities to spot other wildlife on the riverbanks.

2. Mahakam River & Wildlife

The Mahakam River is the vital artery of East Kalimantan, stretching for hundreds of kilometers and supporting a rich ecosystem. A boat journey on this river is the core of your adventure.

Irrawaddy Dolphin (Orcaella brevirostris): The river's primary habitat is home to these rare and endangered freshwater mammals. The Mahakam dolphins, with their rounded snouts, are often seen swimming and playing on the water's surface. Spotting them is a very special experience.
Endemic Birds: The Mahakam River is a paradise for birdwatchers. You can see various species such as Kingfishers in various colors, graceful Herons, Eagles hunting overhead, and iconic Hornbill species.
Saltwater Crocodile (Crocodylus porosus): Although rarely seen directly, saltwater crocodiles are inhabitants of this river. Their presence is an indicator of the river's ecosystem health.
Riverside Villages: Visits to traditional villages along the Mahakam River, such as Muara Kaman or Muara Munai, offer insight into the lives of local communities who depend on the river for transportation, fishing, and culture.

3. Sungai Wain Wildlife Sanctuary & Bukit Soeharto

Located near Samarinda, these wildlife sanctuaries offer additional opportunities to see Kalimantan's wildlife, albeit on a different scale than Tanjung Puting.

Flora and Fauna: Explore the preserved tropical rainforests, which are home to various primate species besides orangutans, such as Proboscis Monkeys in coastal areas, Long-tailed Macaques, and various species of deer and wild boars.
Trekking Trails: Trails are available for you to explore the forest on foot, accompanied by a guide to identify medicinal plants and wildlife.
Conservation Importance: These sanctuaries play a crucial role in protecting the remnants of lowland forests vital for the survival of many species.

4. Dayak Culture & Local Crafts

Beyond its natural beauty, East Kalimantan is rich in Dayak cultural heritage.

Longhouse (Rumah Panjang): If possible, visit a village that still has a traditional longhouse, where many families live together under one roof. This is an opportunity to understand the social structure and lifestyle of the Dayak people.
Handicrafts: Witness or purchase unique handicrafts such as wood carvings, rattan weavings, and beadwork made by local communities. These are authentic souvenirs and support the local economy.

This journey combines elements of adventure, education, and cultural appreciation, making it a rich and multi-dimensional experience in the heart of Borneo.

Travel Tips & Logistics

To ensure your 5-day trip in East Kalimantan is smooth and enjoyable, thorough logistical planning is essential. Here are some tips and important information:

Best Time to Visit

East Kalimantan has a tropical climate with two main seasons: the wet season and the dry season.

Dry Season (approximately June to September): Generally considered the best time to visit. Rainfall is less, making outdoor activities and boat trips more comfortable. The rivers tend to be calmer, facilitating wildlife observation.
Wet Season (approximately October to May): Rain can occur at any time, sometimes heavily. However, this also means the forests are greener and the rivers are fuller, which may attract certain wildlife. Travel might be slightly more challenging due to road and river conditions.

Accommodation

Accommodation options vary depending on the location and your budget.

Major Cities (Balikpapan, Samarinda): A wide range of hotels are available, from business-class to five-star. These are good starting points for organizing your trip.
Along the Mahakam River: The most authentic experience involves staying in local homestays or simple lodges in riverside villages. For a closer experience with nature, consider staying in a neko-neko (traditional house boat) or community-run guesthouses.
Tanjung Puting: If you choose this route, you will stay on a klotok (motorized boat) equipped with simple beds, or in some lodges located near the research stations.

Transportation

Flights: Sultan Aji Muhammad Sulaiman Sepinggan International Airport (BPN) in Balikpapan is the main gateway to East Kalimantan. You can also fly into Temindung Airport (SRI) or Aji Pangeran Tumenggung Pranoto Airport (AAP) in Samarinda.
Inter-city: Travel between major cities like Balikpapan and Samarinda is generally by bus or private car hire (approximately 3-4 hours).
River Travel: Motorized boats (klotok) are the primary mode of transportation along the Mahakam River and for accessing tourist sites in Tanjung Puting. Ferries and passenger boats also serve regular routes on the river.
Private Car/Rental: For exploring land areas, a 4x4 vehicle is highly recommended due to varying road conditions, especially outside major cities.

Preparation and Gear

Clothing: Pack light, sweat-wicking, and quick-drying clothes. Long-sleeved shirts and long pants are recommended for protection against the sun and insect bites. Also pack swimwear if you plan to swim.
Insect Repellent: Mosquito repellent containing DEET is essential.
Sunscreen & Hat: Protection from the intense tropical sun.
Footwear: Comfortable trekking shoes or sturdy sneakers for walking in forests, and flip-flops for relaxing.
Personal Medications: Bring your personal supply of medications.
Electronics: Camera, spare batteries, power bank, and a universal adapter are very useful.
Cash: Although some places accept cards, many transactions in remote areas still use cash. Have sufficient Indonesian Rupiah (IDR) on hand.

Health and Safety

Vaccinations: Consult your doctor about recommended vaccinations, such as Hepatitis A, Typhoid, and Tetanus. Malaria prophylaxis may also be advised depending on the areas you visit.
Drinking Water: Drink only bottled water or water that has been boiled/filtered.
Food: Try local cuisine, but ensure it is well-cooked and served in a clean environment.
Safety: East Kalimantan is generally safe, but always be aware of your surroundings. Follow the instructions of local guides, especially when exploring forests or rivers.

With proper preparation, your 5-day adventure in East Kalimantan will be an unforgettable experience, filled with natural beauty and cultural richness.

Cuisine & Local Experience

A trip to East Kalimantan would be incomplete without exploring its culinary wealth and experiencing local encounters firsthand. Unlike Java, which is more globally known, Borneo's cuisine offers unique flavors influenced by its abundant natural produce and the traditions of its people.

Distinctive Flavors of the Mahakam River

The Mahakam River is not just a transportation route but also a primary food source for the surrounding communities. Freshwater fish are the stars of the region's signature dishes.

Grilled/Fried Fish: Various fresh fish from the Mahakam River, such as Jelawat, Gabus, or Patin, are prepared by grilling or simple frying. Served with spicy sambal terasi (shrimp paste chili sauce) and fresh vegetables (lalapan), the taste is truly appetizing. The experience of eating freshly grilled fish by the river is an unforgettable moment.
Tempoyak: A fermented dish made from durian pulp mixed with spices and sometimes fish. Tempoyak has a characteristic sour taste and is often used as a flavoring for fish dishes, especially Pindang Tempoyak.
Pindang: A yellow-broth fish soup with sweet, sour, and spicy flavors, cooked with various spices like turmeric, tamarind, and chili. Pindang Patin is one of the most popular variants.
Giant River Prawns: These large freshwater prawns are often prepared into delicious dishes, either fried with garlic or cooked with local spices.

Local Cultural Experiences

Beyond cuisine, interacting with local communities is key to understanding the soul of East Kalimantan.

Visits to Traditional Villages: Visiting Dayak villages, such as those in the Apo Kayan region (though further away) or villages along the Mahakam, provides an opportunity to witness daily life, traditional house architecture (including longhouses), and understand their customs.
Community Interaction: Try to communicate with the local residents. Their openness and hospitality often make visitors feel welcomed. Learning a few basic phrases in Indonesian or even a local Dayak language will be greatly appreciated.
Performing Arts: If you are lucky, you might witness traditional Dayak performances, such as the Hudoq dance (a fertility dance) or the sape' music (a traditional string instrument).
Handicrafts: Visit local markets or craft centers to see and purchase handicrafts made by the Dayak people, such as wood carvings, rattan weavings, and bead jewelry. This is a great way to support the local economy and bring home authentic souvenirs.
Traditional Ceremonies (if coinciding): If your travel schedule coincides with traditional ceremonies like Gawai Dayak (harvest festival), it will be a profoundly enriching cultural experience.

Local Beverages

Young Coconut Water: Fresh and always available, it's a refreshing drink under the tropical sun.
East Kalimantan Coffee: Tasting locally grown coffee from Kalimantan is often a unique experience.

Exploring the cuisine and engaging in local experiences not only satisfies your palate but also enriches your understanding of East Kalimantan's culture and people's lives. It is an integral part of an adventure that connects you more deeply with the beauty of Borneo.
