A natural heritage site needs care
UNESCO recognizes the geological and geomorphological value of Ha Long Bay-Cat Ba and also points to tourism management and ecological pressures. The Bay Management Board has issued a plan to reduce plastic waste. These documents place responsibility on both managers and visitors.
What you can do on one trip
Bring a reusable bottle if the operator allows it, keep rubbish until you can dispose of it properly, do not throw food into the water, and do not collect rock, coral, or wildlife. Follow safety instructions on the boat and ask about single-use items. There is no need for grand promises: a careful trip starts with actions you can take now.
