Ao Sangthian is located on the southern part of Koh Samet in Rayong Province. The beach is known for its tranquility and private atmosphere, with soft white sand stretching along crystal-clear waters that sparkle beautifully in the morning sun. The shoreline features natural rock formations, and during low tide, small crabs can often be seen clinging to the rocks—a reminder of the area’s rich coastal ecosystem. Most visitors come here to relax, read, stroll along the shore, or enjoy stargazing at night.

 

The beach lies within the Khao Laem Ya – Mu Ko Samet National Park, helping it retain its pristine natural beauty. Compared with busier areas like Sai Kaew Beach or Ao Wong Duean, Ao Sangthian is far quieter and more peaceful. It suits those seeking calm surroundings without the noise of boat engines or crowds. The beach is well maintained thanks to cooperation between the national park and local businesses.

 

The main accommodation in this area is Sangthian Beach Resort, a seaside resort with a private beach and beachfront restaurant. The resort is shaded by coastal trees and offers various room types including bungalows and villas designed to blend with nature. Guests can enjoy gentle activities such as kayaking, snorkeling, or watching the sunset right from the beach.

 

On some evenings, there are fire shows and live music on the beach, adding a touch of liveliness while keeping the peaceful atmosphere. The resort also provides boat transfer services from Ban Phe Pier and local transport connections to other beaches on the island, such as Ao Phrao and Ao Wong Duean.

 

Getting There From Bangkok, travel to Ban Phe Pier in Rayong, about 200 kilometers away, taking roughly three and a half hours by car. Then take a ferry to Koh Samet (around 30 minutes). From Na Dan Pier, local songthaews or motorbike taxis can take you to Ao Sangthian in about 10–15 minutes. Roads on the island are often steep, so caution is advised when driving.

 

The best time to visit is between November and May, when the sea is calm and the sky is clear. Between June and October, occasional rains and rough waves may occur. Because the number of rooms is limited, advance booking is recommended during long weekends or holidays.

 

Nearby attractions include Ao Wong Duean (1.5 km), known for its wide beach and water activities; Sai Kaew Beach (3 km), the island’s main tourist hub; and Laem Thian Viewpoint (800 m), which offers a panoramic view of the bay. In the main village area of Koh Samet, travelers can find local seafood restaurants, souvenir shops, and local boat services for island tours.

 

Ao Sangthian remains one of Koh Samet’s most serene beaches, preserving its simple charm both by day, when sunlight glistens on the sea, and by night, when the stars reflect on the water. For travelers seeking peace, natural scenery, and a true seaside retreat, Ao Sangthian is one of Rayong’s most rewarding destinations.
