The guide was very good. During the car ride to Ba Na Hills, he told us about the history of Da Nang and Vietnamese coffee. On the way back, the car was late and there was a traffic jam. The guide also brought me a souvenir, a dragonfly that I put on my finger and didn't fall. When we arrived at Ba Na Hills, the guide took very good care of me. The place was very beautiful. There was a sound system that made me feel delighted the whole time. There were a lot of clean and plentiful bathrooms. Unfortunately, I had already bought a ticket to play the coaster, but I couldn't play it because the weather was not good. I recommend buying it on the spot instead.
