In 2025, Ha Long Bay Management Board registered to develop 3 new tourism products in Ha Long Bay. Among these, there are art performances combined with parties at Trong Cave, Co Cave, Trinh Nu Cave; light parties on the sand beach in Ban Chan sand beach area, Tra San area.
In fact, having a snack party in a cave or on a sand beach in the middle of Ha Long Bay is not new, because previously, ship owners in collaboration with travel companies had a pilot and were very successful.
However, after that, this tourism product was suspended until now, although businesses and ship owners have repeatedly proposed reopening to serve tourists.
Meanwhile, some music programs at Dau Go cave were quite successful and at one point, Quang Ninh province also planned to turn Dau Go cave into a special theater in the middle of Ha Long Bay.
One of the reasons why tourism workers' proposals to open new products in caves, including art performances and light parties, have so far been considered for implementation is because there are many different opinions on nature conservation.

However, in interviews with Lao Dong Newspaper, international experts, including experts from UNESCO and the International Union for Conservation of Nature (IUCN), believe that it is completely possible to party in caves, on sandbanks in the middle of the bay. The problem is to have solutions to protect the environment, landscape and especially limit the number of participants.
Previously, luxury parties for tourists in caves in Ha Long Bay were very simple and few people, there were meals with only a few people but the price was very high.
This not only minimizes the impact on the landscape and environment of caves but also brings in a large source of income.

According to some cruise ship owners, if they reopen, in addition to collecting high prices, they should calculate the limit on how many passengers can be served each time, or limit the number of passengers per month, per quarter, per year.
Accordingly, if you pick up enough quantity, stop and do not pick up more even if you pay more. This is also the way to do it in many famous tourist destinations in the world. Doing so will both limit the impact on heritage and increase the value of Ha Long Bay, because only Ha Long Bay has such tourism products and if you want to experience them, you have to even book a year in advance.
