Known as the 'nudibranch capital of the world,' Anilao in Batangas is the Philippines' answer to Indonesia's Lembeh Strait. A muck diving paradise where multitudes of fascinating rare critters—including frogfish, blue-ringed octopus, tiny tiger shrimp, and dozens of nudibranch species—can be found in sandy slopes and mangroves. Close to Manila, making it accessible for weekend dives.
