Bonacaud (Kerala state, India) is the base station of the famous peak, Agasthyarkoodam in the Agasthya hills.

The Agasthya hill range is famous for its abundance of rare herbs and medicinal plants.

Bonacaud (natively called Bonakkad) is now used as trekking base camp to Agasthyakoodam.

It is believed that around 1850 an estate was established on the top of the hill and near to a river named as Sooryakanthi.

Lower-priced tea imports following the implementation of General Agreement on Tariffs and Trade pushed the estate into losses.
