Around 8 kilometers from the temple town of Alampur is a place Gundimalla where you can have a breathtaking view of the confluence of Krishna and Tungabhadra. There are well made ghats for taking bath and if you are able to befriend a local boatman, you can enjoy a ride in Theppa (a local boat). Theppa is like a large basket made of Bamboo. This is used by the local people to travel in the river.
Also, there is no public transport or even share autos to reach the confluence. You have to arrange for your own transport to reach the confluence. Few places the road becomes very narrow but this travel of 8 kms is worth the effort.
