Embark on a back-to-nature adventure as you journey through the thick mangroves of Bintan along Sebung RiveRight alongside the white sand is a surreal crystal-clear blue lake. It's hard to imagine that this crystal blue lake was once just a large crater in an abandoned mining site, but as time went by, it began to gradually fill with rainwater resulting in a "post-apocalyptic oasis" in the middle of Gurun Pasir Busung desert. Take a picture with both sights in the background and you’ll be flooded with instagram likes.r. The dense foliage and interconnected roots of the trees naturally give rise to a thriving community of animals and plants. Witness the agile leaps of macaques and silver leaf monkeys, and colourful kingfishers as you sail across the mangrove jungle on the Mangrove Discovery Tour.
