Set in the backdrop of stunning limestone cliffs, the powdery-white sands of Railay Beach aren't just delightful to admire, but the journey in getting to the beach is also exciting in itself. The towering limestone cliffs cut off mainland access and isolate the stretch of beach from Thailand's mainland, inviting all beachgoers to hop aboard a long-tail boat and set sail into turquoise blue waters, revealing some thick mangrove forests before stepping foot ashore on pristine heavenly sands. Railay Beach isn't just one single beach, but a combination of four beaches, out of which, Phra Nang Beach sure does bask in the glory of being the most stunning, thanks to its pristine sands, majestic rocks and fascinating sea caves.
