From Railay East or West, it's a scenic 15-20 minute walk through or around the headland. Many island-hopping tours from Krabi Town or Ao Nang include Phra Nang Beach as a stop. Once on Railay Peninsula, follow signs or ask locals for the walking path to Phra Nang Beach through the resort area or beach route.

For dining, walk to nearby Railay West or East beaches, which offer numerous restaurants ranging from casual beachfront eateries to resort dining. Accommodation options are primarily on Railay West and East, including luxury resorts like Rayavadee (which fronts Phra Nang Beach), mid-range hotels, and budget bungalows. Most visitors stay in Railay and walk to Phra Nang Beach. For maximum convenience, book resorts near Phra Nang, though these tend to be more expensive given the prime location.

The Princess Cave (Phra Nang Cave) is a sacred shrine dedicated to a mythical sea princess believed to bring good fortune to fishermen and locals.

The legend and spiritual significance make it a distinctive attraction beyond typical beach features. Combined with the beach's crystal-clear waters and stunning karst scenery, the Princess Cave adds cultural depth to what's already considered one of Thailand's most beautiful beaches.
