Ghenh Da Dia lies within the area of Tuy An district, Phu Yen province. This is a special beauty spot comprising many large rocks evenly rising up in their pentagonal shapes; each layer continuously lapping next to one another on a large scale. View from distance, this site looks like a giant beehive. The closer view will make you think of piles of cups and plates in ceramic furnaces.

From Phu Yen, there are various ways to transfer to Ghenh Da Dia. The first option is traveling along the National Highway No.1, about 30km towards the north. Upon reaching Chi Thanh town, turn right and continue to drive about 12km to the east. The second option is traveling by waterway (which takes about 1-2 hours) from ward 6’s port, Tuy Hoa city. Most tourists choose to travel by waterway since they can enjoy the fascinating scenery along the way with islands, beaches.    

Ghenh Da Dia lies close to the seashore. The first impression upon reaching the destination is black rocks lying next to one another looming in continuous blue waves. It seems that there is a magic hand which has arranged such wonderful beauty spot. The pieces of rock are not just shaped like pentagons, but also have other shapes such as hexagonal or round ones.

According to initial research, Ghenh Da Dia is formed during the operational process of a volcano on Van Hoa highland (Son Hoa), about 30km away from the destination.

Visiting Ghenh Da Dia, tourists not only have chance to enjoy the untouched beauty of the rocks, but also to relax on a beautiful beach, which lies to the south of Ghenh Da Dia. The 3km-long beach is featured with crystal clear water and purely-white sandy beach.

Despite of its fame and the number of visitors, Ghenh Da Dia has not received enough investment with no completed tourist site. However, visitors can find the most memorable moments there with interesting self-made activities such as camping, sun bathing, fishing, etc.
