After hotel pickup in Hanoi, journey to Halong Bay by air-conditioned bus. Admire the views as you drive through the Vietnamese countryside, passing rural villages, lush rice paddies, and herds of water buffalo. Then, 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. Your driver waits to take you back to Hanoi to drop you back at your hotel or at a central location (depending on the day).
