It won't be wrong to describe Kerala as a canvas of many colours. Not one or two but a host of spectacular features attract tourists to 'God's own country.' The backwaters of Kerala are probably the only one of their kind in the entire country. The houseboats on the backwaters further adds colour to them. The ancient Indian treasure of Ayurveda flourishes in Kerala. The state is also thronged by wildlife enthusiasts.The most popular is the Periyar Wildlife Sanctuary.
