Can I walk from Narada Boutique Hotel going to The Bund/Nanjing Rd. area??

Yes. From the hotel, you can walk northwest around 1 mile (1.5 km) to get to the East Nanjing Road Pedestrian Street. Then you can walk east along this street 1.2 miles (1.8 km) to arrive at the Bund Area. Notably, there are many stores and restaurants along the street. Most tourists are willing to walk for this distance. So don't worry.
