Miri River is the body of water that splits Miri Peninsula and the mainland Miri, flowing out to sea from inland, curving at Lutong Town. In one particularly popular but inaccurate online map service, the river is incorrectly marked as Sungai Baong. Others references online have confused it with Baram River.
The Miri Long Jetty was a mile long and stretches out into the sea. This jetty was built so that cargo is easily offloaded from ships to Miri at the tip of the Miri Peninsular. The Long Jetty was a considerable place of interest in the 1970 to late 1990s.
