In the morning, we explore Phong Nha's rural villages, surroundings, and calm rivers flowing to the sea. Phong Nha has mainly featured caves, quiet rivers, tiny villages, and its karst mountains. Most villagers live primarily in farming, rice crops, and fruit orchards but only a little fishing. 

After lunch in Dong Hoi, we'll rest on the transfer for 1 hour to Vinh Linh Dist, then continue to explore the scenic countryside to Vinh Moc tunnels. The seaside areas offer idyllic countryside of blooming trees and vast fields, providing beautiful backdrops and fish farming when we ride down the coast. Visit Vinh Moc Tunnels, stay on coastal back roads, pass locals' sandy beaches, and take plenty of photos along small fishing villages to Hien Luong Bridge. The last visit of today is to the famous Museum of Hien Luong Bridge that knows the 17 parallel divided Vietnam in 1954 until the war ended in 1975. We'll transfer to Dong Ha in the late afternoon
