Sentarum is the only seasonal lake which lies in a primary swamp in West Kalimantan. It’s located in a basin close to Kapuas River. The water of the lake has reddish-black shades due to the amount of tannin which comes from the peat forest surrounding the lake. At the peak of dry season, this lake becomes a wide stretch of dry soil.
It could be reached using the route Pontianak-Sintang-Semitau by public transportation in about 11 hours. From Semitau to the site, visitors can use the motorboat to Lanjak.
