Mui Ne has 2 golf courses.
The first one is in Sealinks on top of the sand dunes of Mui Ne.
The second one is the Ocean Dunes Golf Club in Phan Thiet at the DuParc Phan Thiet Ocean Dunes & Golf Resort by the beach.
Below are a few specificities about Mui Ne:

• The temperature in Mui Ne gets high during the day, so you should plan starting your game early in the morning
• The wind in Mui Ne can be very strong, especially in winder time. As a result, don't be surprised by the surprising distance you will reach or the incredible slice of your balls.

I have been playing in the Sealinks Golf. I am far from being a good player and several holes were challenging for my level. You will face trees, bushes, water ponds, hilly ground and wind. I lost a few balls of course but the scenery is beautiful and really worse it.
I have also played at the Ocean Dunes golf and it has been challenging as well with all sorts of obstacles, however I think that I lost less balls than at Sealinks. In conclusion I would say that it is an easier golf course. This golf is also very well maintained and offers a great scenery.
