Nagarjuna Sagar dam area is beautifully managed by local administration. However, reaching after rainy season is best option. The best season is from August to December. Nearby places are also impressive. I got good collection of several tourist attractions closer to Dam area from https://indiantouristspot.com/nagarjuna-sagar.html website. I thing it is good for travelers to gather the information related to special tourist place. I got good help from this website. Hope people will also get ample of knowledge about Nagarjuna Sagar Dam.
Route to dam is good as well. Clean roads.
