The undulating Banasura Hills in Wayanad stand as sentinels to the biggest earth dam in India, the Banasura Sagar dam. Just a few kilometres away, in rugged hilly terrain, stands the Banasura Hill Resort, said to be the biggest earth resort in the country. The rammed earth walls of the resort is built with mud from the very site that it stands on. Earth scooped out from the hill slope to create a plain was used to build the resort. Local tribals were called in for the labour and their expertise in building with mud was also tapped.
