Sempu Island, located in Hindia Ocean, and takes around 4 hours road trip from Malang.
Eventhough it is located in Hindia Ocean, it surrounds by other small islands which protect it from the huge dramatic waves. We can safely take a trip using the fisherman boat. I could say that this place is still virgin. Seeing the water, watching the wave burst into the corals, big clean sky. It was beautiful, and the 4,5 hours trip by foot at night felt worth to be done.
