Today is a long day for us to explore the magnificent mountainous area scenery and stop at the Sea Cliff of Stone Plates. “Locals called Ganh Da Dia” The rocks are dark lava columns with roughly flat surfaces of different shapes. 

After a leisurely breakfast, a 30-minute transfer takes us to rural Dist to start this morning ride. We cycle through tiny villages and rice paddies and stop at local families making bamboo brackets before we undulate on paths, then ride along the small river to La Hai. The routes offer amazing sceneries along back roads, charming villages, and a valley of rice paddies. We continue the day riding along the railways, racing with Reunification Express's trains, and visiting a beautiful pagoda. Lunch en route to Tuy Hoa. Following lunch, the quiet back road along the sleepy river and dirt tracks along the ocean give us more chances to meet locals along fishing villages with many basket bamboo boats. There are many stops at tiny towns for a coffee break and fruit. Then we continue cycling on the hilly countryside road to Da Dia Reef.

Ganh Da Dia is a seashore area of uniformly interlocking basalt rock columns located along the coast in An Ninh Dong Commune, Tuy An District, Phu Yen. The site is about 100 meters wide and 250 meters long, with an estimated 35,000 columns of basalt rocks. The rocks are dark lava columns with roughly flat surfaces of different shapes - round, pentagon, hexagon, polygon, etc. Locals call Ghenh Da Dia. These rock columns were created from volcanic eruptions millions of years ago; when the molten basalt flows met cold water, they solidified and shaped these rare polygonal formations due to thermal contraction effects after spending time seeing incredible rock shapes made by nature. We ride on the small concrete path through rice paddy fields and a lagoon to An Hai. We ride through tapioca farmlands and sweet potatoes and then to the coast to Tuy Hoa City.
