Set sail on a scenic cruise around Halong Bay and discover its UNESCO-listed natural wonders—an expanse of glittering turquoise water dotted with jagged karst formations, soaring sea cliffs, and rocky islands. Stop at a calm area of the bay to enjoy sea kayaking or a bamboo boat ride (choice of one activity), affording a closer look at the unique landscapes. Tuck into a delicious seafood lunch on board as you gaze out across the bay. After lunch, cruise through Heavenly Cave (Thien Cung), before sailing back to shore.
