This was my second visit to Ha Long Bay, and this time I chose a two-day, one-night itinerary. Watching the sunset from the boat and then the sunrise the next morning was beautiful. The meals on the boat were excellent; I'm worried I gained weight! The afternoon itinerary included a trip to Yen Tu Mountain, and I must say this was a very challenging journey, full of stairs that will definitely make your legs ache. However, the effort was worth it; the view from the mountaintop was stunning, and the weather was perfect, giving me a chance to take photos with a blue sky and white clouds. I think this trip was excellent.
