Alas Purwo National Park, National park at the eastern tip of Java, Indonesia

Alas Purwo sits at the easternmost point of Java and protects roughly 43,420 hectares of land that includes mangrove forests, coastal stretches, savanna landscapes, and tropical rainforest. The protected area extends along the shoreline and inland, where different habitats transition into one another and support a wide range of plant and animal life.

Alas Purwo was designated a national park by Forestry Ministerial Decree No. 283/Kpts-11/1992, dated 26 February 1992, covering 43,320 hectares on the Blambangan Peninsula. The name means "first forest", from a Javanese legend that the earth first rose from the ocean at this spot. A 2015 zoning decision split the park into core, jungle, rehabilitation, traditional, utilisation, special and religious-cultural-historical zones.

The Luhur Giri Salaka temple inside the reserve serves as a spiritual center for Hindu worshippers who travel here for ritual observances and ceremonial offerings. Pilgrims visit regularly to perform prayers and honor the sacred connection between this coastal landscape and their faith traditions.

Visitors can join guided tours offered between April and October when weather conditions make outdoor exploration easier. Certain areas remain accessible to guests, while other zones stay protected for wildlife conservation.

The savanna of Sadengan, about 80 hectares, is where banteng herds gather in the morning and afternoon to feed. In April 2004 only 57 banteng were counted there, down from an estimated 80 to 100 the year before; by August 2010 the count had risen to 73. Poachers set traps outside the park in the dry season, when the animals wander out in search of water.
