Pantai Lembupurwo, Coastal destination in Mirit, Indonesia

Pantai Lembupurwo is a black-sand beach in Lembupurwo village, Mirit, Kebumen, on the border with Purworejo. A lagoon at the mouth of the Wawar River, separated from the sea by a stand of cemara udang trees, lies behind the shore. Above it rise wide, active sand dunes, the tallest among Kebumen's beaches.

The beach formed through the natural accumulation of sand and sediments shaped by the waves of the Java Sea. Over time, a lagoon developed between the sand dunes, retaining water and defining the coastal landscape.

Every year in the Hijri month of Syawal, seven days after Idul Fitri, Mirit residents hold the Grebeg Rowo festival at the beach. The return-home traffic of Lebaran brings crowds rather than emptying the coast, and the event has become a tradition for the district.

The beach lies about 30 km southeast of Kebumen town and roughly 1 km from the Daendels road, with the JLSS about 500 m away. Facilities are run by the village and are limited outside holiday periods. A bamboo bridge crosses the lagoon toward the casuarina grove and the beach.

The lagoon is the mouth of the Wawar River, a brackish pool cut off from the sea by a belt of cemara udang (casuarina) trees. Mangroves grow along its edge, and a bamboo footbridge crosses it toward the forest and the beach.
