While Railay is part of the Thai mainland on the Andaman Sea side, it looks and feels like an island. The karst topography has left it isolated and devoid of road access, meaning the only way to get in is by boat. At Railay, there are no roads, only footpaths. No buses, no cars, just long-tail boats. Although it’s connected to the mainland, the spectacular Phra Nang Peninsular is effectively cut off from the rest of Krabi by limestone headlands and steep jungle valleys; the only access is by sea. The very picture of tropical paradise, with no roads and no hassle, Railay offers lazy days, adventure forays and chilled-out evenings with an apparent reason for its fame – it’s just spectacular.
