Did you know that Lake Sentarum National Park is one of Asia’s most unique wetland ecosystems, transforming dramatically between wet and dry seasons? This hidden gem in West Kalimantan, Indonesia, spans an impressive 132,000 hectares and serves as a crucial water regulation system for the entire Kapuas River basin – Indonesia’s longest river. When flooded during the wet season, the park becomes a mesmerizing network of interconnected lakes, creating breathtaking reflections of surrounding forests that seem to mirror another world entirely.
About Lake Sentarum National Park
Lake Sentarum National Park sits in the remote Kapuas Hulu Regency of West Kalimantan. This remarkable ecosystem experiences dramatic seasonal changes, with water levels rising and falling throughout the year. During the wet season, the area transforms into an extensive network of lakes, while the dry season reveals forests, meadows, and distinct waterways.
The park is not only ecologically significant but also culturally rich. Indigenous communities, including Dayak and Melayu groups, have inhabited this area for centuries, developing sustainable fishing practices and a deep connection to the ecosystem. Their traditional knowledge has played a crucial role in preserving this natural wonder.
With over 240 fish species, 250 bird species, and endangered wildlife including orangutans and proboscis monkeys, Lake Sentarum offers nature enthusiasts an unforgettable experience away from Indonesia’s more touristy destinations.

Best Time to Visit & Weather Tips
Lake Sentarum experiences two distinct seasons that dramatically transform the landscape:
Wet Season (November-May)
During these months, the area transforms into a vast network of interconnected lakes. Water levels rise significantly, submerging forests and creating a magical landscape of reflections. This is the best time for boating and experiencing the full wetland ecosystem.
Dry Season (June-October)
As water recedes, the landscape changes dramatically. Some lakes dry completely, revealing meadows and forests. This season offers better opportunities for wildlife viewing and hiking. It’s also easier to visit the indigenous communities.
Many locals recommend visiting twice – once during each season – to fully appreciate the remarkable transformation of the ecosystem. The ideal times are April-May (late wet season) and August-September (middle of dry season) when conditions are most stable.
Traveler Tip: Pack lightweight, quick-dry clothing, insect repellent, and waterproof bags regardless of when you visit. Even during the dry season, sudden rain showers are common in this tropical climate.
