I am a travel writer and I highly recommend Philippines if you are someone who seeks romantic getaway and adventure. The pristine white sands here in my country so to enumerate are Boracay, Bantayan and Malapascua Island, Siargao (best for surfing) comparable to Bali, Indonesia are really breathtaking and awesome.
Besides those beaches, Philippines is a country rich with cultural heritage starting from the Spanish era where artifacts are stored in museums, a hundred or so monuments, forts and churches.
And most of all, Philippines is the home of the friendliest people and it would not be difficult for you to travel since most Filipinos speak the universal language and they are very much willing to offer you help for directions and the like!
