Where is Poto Tano Harbor Located?

Poto Tano Harbor sits at the western coast of Sumbawa, within West Sumbawa Regency, West Nusa Tenggara, Indonesia. The harbor directly faces Kayangan Harbor in East Lombok, separated only by a narrow sea channel. This strategic location makes Poto Tano the “front door” of Sumbawa Island — a must-pass hub for travelers crossing from Lombok by ferry, speedboat, or sailing yacht.

The surrounding scenery is breathtaking: turquoise waters framed by small green hills and several tiny islands, such as Kenawa Island, which can be clearly seen from the port area. On clear days, you can even see Mount Rinjani from afar, standing tall across the Lombok Strait.
