Marmala waterfall lies a few kilometres away from Erattupetta, in Kottayam district, Kerala, India inside a private estate, .
 It is exactly 7 km from Teekoy rubber estate.
 From here a private vehicle can take you further 2 km after which the road is not motorable.
 Only a four-wheel drive (4x4) Jeep can go through the narrow path, often passing over the uneven rocky terrain where no car would go.

 To reach the falls one has to get off the jeep and trek through the estate over the slippery rocky path.
 The waterfall is about 60 metres in height, falling into a 12-meter deep pool and joins the River Teekoy way down.
