One of the most under-visited spots on the Poncokusumo road to Mount Bromo is Banyu Biru. The spring that flows from one of the river intersections creates a small waterfall with very cold water. The flow of water creates a natural pool with clear and bluish water. It is not surprising that most tourists refer to this place as their own private swimming pool. Furthermore, this place is also surrounded by lush trees that make the atmosphere more comfortable. Some tourists visit this place while bringing folding tables and chairs so that they can sit and relax under the lush trees while enjoying coffee on the riverbank. To reach Banyu Biru, tourists must walk from the parking area along the forest and river with big rocks. It doesn’t take long, just a few minutes to walk along while enjoying this stunning natural beauty.
