Bai Tu Long Bay, located in the northern part of Vietnam, to the east of Halong Bay (Quang Ninh province), is a stunning natural landscape known for its pristine natural beauty and crystal-clear waters. This off-the-beaten-path location is a hidden gem that offers a unique and authentic experience to travelers seeking to escape the crowds of more touristy areas. If Halong Bay is too busy for you, opt for this overnight cruise in Bai Tu Long Bay equally beautiful, and a lot less crowded. Besides admiring the spectacular karst rock formations, enjoy a rowing boat or kayaking, explore Thien Canh Son cave, feast on fresh seafood, and join in activities from tai chi to squid fishing.
