San Diego has the largest urban cultural park in the United States, Balboa Park. The entrance to the gate seems to have contrasted with the ancient Spanish colonial era and the coastal city outside. The park is full of Spanish colonial revival-style gorgeous museum buildings and excellent gardening. Designed, the park brings together 15 museums including human history, natural history, photography, art, cars, flying, etc. The museum has two museums, the San Diego Natural History Museum and the Fleet Science Center. The design of the museum is very attractive. It is a hand-to-hand touch to explore some areas that children have not touched before. It is very suitable for taking children to study.
