Let me answer this question, Sanya is a typical tourist city, to say that those attractions must go, here I give some of my personal opinion.
I think Sanya must go to four places, these four places have their own characteristics. The first is the island, to Sanya must experience the island, Wuzhizhou Island is a good choice, the time on the island is very slow, you can enjoy a very good tourist life; the second is the tropical rainforest, this is not really let you go deep into the rainforest, but to go to some of the attractions with the characteristics of the tropical rain, the Yalong Bay Tropical Paradise Forest Park is a good choice, you can breathe the natural oxygen in that, very satisfying; the third is the Sanya's one of the most iconic attractions, the end of the world must go, this attraction in fact nothing special, but to the Sanya tour, not to see here will have regrets; the last one is to eat, I recommend going to Sanya's locomotive, go to eat seafood in Sanya, to feel the kind of ten thousand people to eat seafood of the grandeur.
It should be noted that it is because Sanya is a tourist city, so the strange problems of tourism in Sanya can be found almost all. So to Sanya to go to the above places, but also pay extra attention not to be slaughtered. In addition, in fact, I personally think that Sanya's prices are high, although the scenery is beautiful, but in fact, really all play down, it will cost a lot of energy and financial resources, so if not particularly wealthy, I would recommend to go to other cities in Hainan, perhaps the same amount of money, to be able to play happy.
I have been to Sanya many times, are some tourist activities, the real Sanya but recently this year because of the previous years of tourism is too rampant, is also changing, I have also been more than a year have not been to Sanya, so may also have changed a little.
Lastly, the most pertinent advice is that it's okay to go to Sanya, but make sure you streamline the attractions you want to visit and see some reliable ones, otherwise the journey will be very exhausting for you, and that's what I'm going to share in the hope that it will help people who want to go to Sanya.
