You don't need to buy the ticket 3$ and go to the tourist area, nothing to see on the top, hire a motorbike and take the road to mountain pass road. So impressive. Specially in daylight, you will have a lot of beautiful pictures. Please take a look in my picture, you will see how beautiful, majestic vietnam mountains are. You have to visit this when you're in Sapa, but don't go the the early morning, the fog is too much, can't see anything. Best time to go from 10am to 2pm.
