The train journey from Vizag to Araku is a memorable experience with 46 tunnels, several bridges through lush green valleys. Araku is famous for the mustard flowers that change the landscape of the valley from green to yellow in the months of November & December. Several accommodation facilities are available here. AP Tourism runs very good resorts in Araku, called Valley Resort (also called Yatri Nivas).
