A low river mist parts as you step onto the dragon boat at Phong Nha’s jetty; limestone cliffs rise like folded pages, and the sonorous drip of cave water seems to count the seconds. The day from Huế unfolds as a corridor of changing scenery: paddy fields, wartime landmarks and finally the karst hollow where Son River threads into the mouth of Phong Nha Cave.

Boat motion and balance
Bring a small stabilizing backpack and keep shoes on when boarding — boats can pitch, especially when entering cave mouths.
