Erra Matti Dibbalu, which looks like a mini Chambal Valley literally means red mud hillocks. Locater near Bheemunipatnam, the red sand dunes with occasional patches of green trees were once up to 40 mts high. These are flattened to a height of 15m due to course of various constructions that came up along the Bheemli beach. The million year old vast stretch of red hillock covered by green vegetation with blue waters of the Bay of Bengal on one side provides a picturesque feast for the visitors.
