I feel like I'm betraying a well-guarded secret by telling people about this secluded slice of paradise, but it's bound to be discovered sooner or later. Malapascua, a tiny little island off of Cebu's northern tip in The Philippines, is known as one of the best dive destinations in the world - it's the only place on earth where you can swim with thresher sharks - and also plays host to one of the prettiest little beaches in the world, a grotto on the western part of the island that offers sensational sunset views and a chance to watch the fishermen do their thing against a setting sun.
