According to me 2-3 days is the ideal duration of a trip in Vizag. You can take a day to all the points of interest in Vizag city. Additionally, you will need a day more to take a trip to the Araku Valley and other points of interest like Tyda Park and Borra Caves.
3 days is much needed to visit the whole of beach City, coastal city Vishakapatnam. I will share some offbeat spots see if it is useful for your travel. Duduma falls

Hello, Vizag is a beautiful city with a splendid combination of hills and ocean. Three days is quite good time to explore. The most important thing to be noted is one must visit to Araku valley which is a mesmerising valley. Araku valley is 114 km from Vizag. The journey from Vizag to Araku via train is an amazing experience. I strongly recommend to explore Araku valley which will take 2 day to explore.
