Railay (Thai: อ่าวไร่เลย์), also known as Rai Leh, is a small peninsula between the city of Krabi and Ao Nang in Thailand. It is accessible only by boat due to high limestone cliffs cutting off mainland access.

East Railay Beach is the docking point for boats arriving from Krabi. The East Beach is primarily covered in dense mangrove which is unsuitable for swimming. On the northern end of the waterfront there is a commercial area along a boardwalk/promenade.
West Railay Beach, connected to the east side by paths through the large resorts or by trails through thin jungle cover, is the primary destination for beach-goers in Railay. The beach, as pictured in the panorama below, is flanked by high limestone cliffs on either side. Longtail boats are available to hire for transport.
