This town will be on the way to go to Hoi An.
If I have enough time I will then stop there. It is located 3 hours away from Hué if we take the bus which takes the tunnel. However, if you rent a car or take a taxi, you can take the mountain paths in the direction of Hai Van pass also called the mount of the clouds. It is longer but the countryside is worth it:
On the way down, there are apparently some ponds where there are some kind of restaurants. Some travelers really advised me to stop there to eat some grilled oysters and shells.
There are not too many things to see in the town, but places such as the Marble Mountains are good to discover and they are on the way to go to Hoi An.
Also, I will see if I have time to stop in the Son Tra Peninsula and visit the Monkey Mountain in scooter and the famous beaches around during a day.
