You arrive in late afternoon light along Da Nang’s coastal road — the Lady Buddha rises above the headland, white stone catching the sun while the sea pushes its own rhythm against the shore. The tour moves inland to the Marble Mountains: limestone and marble outcrops that pierce lowland rice paddies, caves cool and shaded, stairs and viewpoints that reward a steady pace. By evening the scene changes to Hoi An, where paper lanterns take over the sky and the Hoài River guides your steps along old merchant houses and the arched silhouette of the Japanese Bridge.
