The tour guide added me WhatsApp, saying that the weather is not very good to upgrade the power umbrella for free, it is better to fly in the morning or afternoon, the driver will pick you up at 7 am, bring your passport photo, you can wear clothes and shoes. The first time I flew, I let myself take the Go pro video, which was very interesting, and the Nha Trang coastline was beautiful. The base has water, drinks and snacks, the video is directly guided to the mobile phone, and then certificates and gifts are issued. It is a great experience, the key is not expensive, and the price is very high.
