At Railay there are no roads; only footpaths. No buses, no cars, just longtail boats. Although it's actually 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.
