Aired (April 29, 2017): Para sa mga katutubong Tagbanwa, tinuturing nilang banal ang lawa ng Kayangan sa Coron, Palawan. Ayon sa kanilang paniniwala, binabantayan daw umano ang nasabing lawa ng mga anito, na kung may mga nais pumasok dito ay kailangan muna silang pahintulutan. Isa ito sa mga pangunahing destinasyon ng mga turistang pumapasyal sa Palawan, hanggang sa ipasara ito noong Marso nang may dalawang turistang biglang naglaho. #GMANetwork #GMAPublicAffairs
