We are very happy we booked this 4-day tour. Our guides were very knowledgeable, both on the sights we were seeing. Although the time on car from Hanoi to Ha Giang lost much time, it gave amazing scenery when reaching Ha Giang as well as along road. Hoang Su Phi terrace field is amazing. the Ha Giang Loop is definitely one of the most memorable. Our drivers were super friendly and were always happy to accommodate us. Homestays were nice. We love photograph so we kept asking to stop so we could take some photos and everything was very flexible for our trip. Dong Van karst plateau geopark is a must-see and this tour is a great way to reach it. I highly recommend it!
