Most travel is currently limited to escorted cruises to the Xisha Islands departing from Sanya, offering visitors rare access to untouched atolls, white sand beaches and vibrant marine life. Due to their strategic location and environmental sensitivity, independent travel is not permitted, and visitor numbers are strictly controlled.
