How to travel from Sanya to Xisha Islands?

Conventional channel: Go to Haikou Office of Xisha Working Committee and apply for Xisha Islands Entry Permit in the name of inspection. After obtaining permission, take the Qiongsha No.2 supply ship on the 28th of each month until the end of the month. The departure point is Wenchang Qinglan Port, and the destination port is Yongxing Island in Xisha. The voyage is about 16 hours. This is the most formal and safest way to go to Xisha, but in order to ensure a berth, you should take some channels at least half a month in advance. Otherwise, it will be delayed until next month's shipment date.

Alternative channels: Hainan Wenchang, Qionghai and Lingshui Wharf charter fishing. This kind of trip is the most fresh and interesting for ordinary tourists, but the cost will be higher and the sailing time will be long. Because fishing boats are small and have weak ability to resist wind and waves, tourists will have a greater seasickness reaction. Suitable for young people with strength to do sea experience tourism activities. The inconvenience and limitation of using chartered fishing boats to travel to Xisha is that it is impossible to apply for an island entry permit (actually, it is an island entry permit for Yongxing Island). You can only visit the islands outside Xisha. ?

Special passage: Sanya Yulin Military Port has regular or irregular supply ships to Xisha; There are also transport planes (usually Yun Qi) flying to Xisha at Sanya, Lingshui and Calais military airports. The two military channels, warships or military aircraft, depend on the relationship with the troops. Political censorship is very strict and only a few people can do it.
