Before visiting Castaway Island, keep in mind that the island is quite remote, with limited amenities. It’s important to bring essentials such as sunscreen, swimwear, and water shoes if you plan on participating in water activities. While the island offers basic facilities for visitors, it’s not as developed as other Halong Bay destinations, so you should be prepared for a more rustic experience. The island’s isolation makes it ideal for those looking for a quiet retreat, but it also means there are few services on the island, so be sure to pack anything you might need for the day.
