Bai Tu Long Bay Vịnh Bái Tử Long
The bay east of Ha Long
The bay east of Ha Long: take one of ten boat routes from Ao Tien or Cam Pha. An April 2025 provincial report charges no entrance fee, only the boat and the port. Three connecting routes leave from Ha Long route 4. Use it when you want a quieter day than the main caves.

Three more routes connect Hạ Long route 4 to Vân Đồn and to Cẩm Phả. A January 2026 patrol note still folds Bái Tử Long into the Hạ Long watch. You reach this bay by boat from Ao Tiên or Cẩm Phả. The park board is in thôn 8, đặc khu Vân Đồn.
