Local legends surrounding the formation of this lake add to its allure for tourists seeking peace and folklore. ## Key facts - **address**: Kampung Linggang Melapeh, Linggang Bigung District, West Kutai Regency - **entrance fee**: Rp 10,000 per person - **opening hours**: Every day, 08:00 - 17:00 # Exploring the Charm of Aco Lake: A Hidden Gem Above the Hills of West Kutai West Kutai Regency in East Kalimantan is not only known as the cultural heart of the Dayak people but also holds stunning geological and ecological wonders. One of the prominent destinations is **Aco Lake**, a natural lake located on the hilltop of Kampung Linggang Melapeh, Linggang Bigung District. Unlike many lakes in Kalimantan formed in lowlands or swamps, Aco Lake offers a unique landscape due to its elevated location, providing a different perspective on Borneo's natural wealth. ## Geological Uniqueness and Landscape Aco Lake possesses very specific characteristics. Situated at an altitude of approximately 300 to 400 meters above sea level, the lake is surrounded by dense secondary forests and green hills. Its surface area reaches about 5 to 10 hectares with considerable depth in its central part. One of the most captivating natural features is the changing color of its water, depending on the intensity of sunlight and the reflection of the surrounding vegetation. On a bright morning, the lake's water tends to be a calm greenish-blue. Due to its high location, mist often blankets the lake's surface in the early morning, creating a mystical and magical atmosphere rarely found in other water tourism destinations in East Kalimantan. Gentle breezes blowing through the large trees provide natural coolness, making it a perfect escape from the scorching tropical weather. ## Preserved Ecosystem and Biodiversity The ecosystem around Aco Lake is part of a well-preserved tropical rainforest. The vegetation surrounding the lake is dominated by large Kalimantan trees such as Meranti and various types of climbing plants. The presence of this forest serves as a natural water catchment area, maintaining the lake's water volume stable throughout the year. For birdwatchers, Aco Lake is a small paradise. Various endemic bird species of Kalimantan are often seen flying low over the water surface or perching on tree branches that hang over the lake. Furthermore, its aquatic ecosystem is inhabited by various types of local freshwater fish. This biodiversity is an indicator that the environmental quality at Aco Lake is still in excellent condition, far from industrial pollution or domestic waste. ## Outdoor Activities and Tourist Experience Aco Lake offers various activities that combine adventure and relaxation. Visitors can enjoy the beauty of the lake in the following ways: 1. **Exploring by Boat and Paddleboat:** The management provides rental facilities for traditional boats and paddleboats. Paddling in the middle of the lake while enjoying the forest's tranquility is a very meditative experience. 2. **Light Trekking and Hiking:** The paths around the lake allow tourists to walk and explore the forest edges. The hilly terrain provides a light yet refreshing physical challenge. 3. **Nature Photography:** With a backdrop of dense forests and reflections of clouds on the water surface, Aco Lake is a favorite spot for landscape photographers. Sunrise moments are the most sought-after to capture the stunning color gradients of the sky. 4. **Family Picnics:** There are shaded areas under the trees often used by visitors for picnics while enjoying their packed meals, creating a sense of togetherness amidst the open nature. ## Best Time to Visit To get the maximum experience, the best time to visit Aco Lake is during the dry season, between June and September. During this period, the access roads tend to be drier and the sky is usually clear, allowing visitors to see the clarity of the lake's water perfectly. Visits in the morning, around 06:00 to 09:00, are highly recommended for those who want to enjoy the morning mist phenomenon and the purest air. Conversely, the afternoon offers a calmer and more romantic atmosphere as the sun begins to set behind the hills of Linggang Melapeh. ## Conservation and Environmental Protection As a vital natural tourism asset, Aco Lake is under the strict supervision of the local indigenous community and the regional government. Awareness of the importance of maintaining the lake's cleanliness is very high. Visitors are strictly prohibited from throwing trash into the water or damaging the surrounding vegetation. Conservation efforts also focus on protecting the forest around the lake to prevent soil erosion that can lead to silting. Its status as a community-based tourism destination ensures that any economic activities generated also contribute to the environmental preservation of the area. ## Accessibility and Facilities Reaching Aco Lake requires a challenging yet rewarding journey. From the capital of West Kutai, Sendawar, the land journey takes about 45 minutes to 1 hour by two-wheeled or four-wheeled vehicles. The road to the location is quite good with asphalt, although there are some steep inclines and sharp turns typical of hilly areas that demand driver vigilance. Facilities in the Aco Lake area are continuously being developed for tourist convenience. Currently available are: * Adequate parking areas for cars and motorcycles. * Gazebos or huts for resting by the lake. * Public toilets and sanitation facilities. * Local stalls serving snacks and drinks. * A small pier as a departure point for boat rentals. ## Conclusion Aco Lake is not just an ordinary tourist destination; it is a symbol of harmony between nature and the lives of the people in West Kutai. Its unique location on a hill makes it an "oasis above the clouds" for anyone wishing to escape the hustle and bustle of modernity for a while. With its pristine ecosystem, clean air, and eye-pleasing scenery, Aco Lake must be on the top visit list for nature lovers exploring East Kalimantan. Preserving its sustainability is a shared responsibility, so that this natural wonder can continue to be enjoyed by future generations.
