  • It's advisable to book sightseeing route No. 1 or a tour package instead of renting a private boat solely for cave visits, as the costs can be quite high. Many cruises offer limited trips to this location; therefore, consider booking the Bhaya day cruise or Halong Sen day cruise.
  • Dress in comfortable attire and sturdy shoes, and bring water with you as the journey can be physically demanding.
  • Make sure to capture plenty of photos in the central area where colorful lights create effective photo opportunities. The lighting is more subdued in other sections of the cave.
