Once you arrived in Semporna, you will realise that there are many island day trips that you can hop on to. One of them is the Tun Sakaran Marine Park day trip. The marine park consists of several islands including Bohey Dulang Island, Mantabuan Island, and Sibuan Island—all of which you will visit on this trip. The trip starts with a short 1-hour hike up Bohey Dulang to see the panoramic view of the whole marine park. After lunch, you will then proceed to Mantabuan and Sibuan for your snorkelling or scuba diving sessions.
