A cluster of islands on the vast expanse of the Vembanad Lake, Kochi, one of the finest natural harbors in the world, is more popular as the Queen of the Arabian Sea. Half the fun of visiting Kochi is going about in the local ferries. A conducted cruise through the winding waterways will take you to several quaint spots including the picturesque islands of Bolgatty, Vypeen, Gundu and Vallarpadam.
