The grandmother, named Popong Otje Djundjunan, is a member of the Indonesian House of Representatives and a Golkar politician.
Djundjunan was the first Indonesian woman aged 80 years to be able to climb the Piaynemo top, Yusdi Lamatenggo, head of the Raja Ampat tourism office, stated here, Monday.
Most seniors climbing the stairs to Piaynemo top on the island are aged between 50 and 60 years.
The Raja Ampat tourism office presented a certificate to Djundjunan for being the oldest tourist to have climbed the top.
Djundjunan said Piaynemo is the most scenic tourist destination in the world.
The lawmaker has urged the West Papua provincial government and people to protect and preserve the environment of Raja Ampat.
Piaynemo Island is one of the most epic spots in Indonesia and the world. The island comprises several small islands covered by a thick green carpet of dense forests and surrounded by crystal-clear, turquoise waters.
Raja Ampat, which literally means "Four Kings," is located in the Coral Triangle, the heart of the world`s coral reef biodiversity.
The seas around Raja Ampat Isles are home to the richest varieties of species in the world, including 75 percent of all known coral species.
The Raja Ampat archipelago encompasses 15 thousand square miles of land and sea. There are around 1.8 thousand isles in Raja Ampat District.
The name Raja Ampat, or "Four Kings," is derived from a local myth. It has four major islands -- Waigeo, Salawati, Batanta, and Misool -- which are home to ancient rock paintings.
Raja Ampat is not only popular for its beautiful marine views but also for its forests where the birds of Paradise dance and sing every morning.
The district is home to over 300 bird species. Of the total, 94 were protected and 11 are endemic ones, such as birds of Paradise, locally called the birds of Cenderawasih.
