But our company occupied the beach. Many of my friends swam in the river, but I didn't. 

Also one my friend injured her leg when she was jumping from the rock and we should look for a surgery. I asked in the bar that was next to the place where we were and then we got to know that there is one not so far from there. So we went there and she got some help there. 

The water in the river is not very clear because of trash and wastes from the factories, so we were afraid of she could got some infection. 

Hope all is okay... 

But still we were walking a lot and saw many beautiful places there, so the trip was nice :)
