Kerala was named one of "50 destinations of a lifetime" by National Geographic Traveler in 2000.
“A cruise along the mirror-still lagoons, picture-book lakeside, palm-fringed canals and shimmering rivulets of `God's Own Country' is the most enchanting holidaying experience in the country. With a cruise along the palm-fringed waterways turning to be part and parcel of holidayers' itinerary, the traditional kettuvallam has emerged as the mascot of Kerala Tourism.”
