Ao Kiu, Koh Samet is one of the most beautiful and tranquil beaches on Koh Samet, Rayong Province. Hidden in the southern curve of the island, this serene bay embraces visitors with soft white sand, crystal-clear blue water, and the peaceful rhythm of waves lapping gently against the shore. Often called the “Bay of Two Lights,” Ao Kiu is uniquely positioned where visitors can witness both the sunrise and sunset from the same spot – a rare experience on a small island like this.

 

The bay is divided into two areas: Ao Kiu Nai and Ao Kiu Nok. Though located side by side, each has its own charm. Ao Kiu Nai is quieter and surrounded by small rocky hills and lush greenery, while Ao Kiu Nok opens toward the wide horizon, making it an ideal spot to enjoy the evening sun. In the morning, golden light dances across the calm water; by evening, the sky glows orange and pink, reflecting softly on the sea – a sight that captures every heart.

 

Ao Kiu’s beauty lies in its simplicity and stillness. The crescent-shaped beach curves along the bay, lined with fine, white sand that sparkles in the sunlight. The clear turquoise water allows you to see small schools of fish near the shore, and the coral reefs remain well-preserved, offering great snorkeling opportunities for those who love marine life. The gentle sounds of the sea create a peaceful melody that invites you to linger and relax all day long.

 

Popular activities at Ao Kiu include swimming, snorkeling, and kayaking to nearby bays such as Ao Wai or Ao Pakarang. The morning is perfect for a seaside stroll, while the evening offers a breathtaking view of the sunset from the rocky western edge of Ao Kiu Nok. As the sun slowly sinks beneath the horizon, the sea turns golden, painting a romantic and unforgettable scene.

 

For those seeking luxury and tranquility, Paradee Resort – often regarded as the most beautiful resort on Koh Samet – sits right on Ao Kiu. Designed in harmony with nature, its private villas feature thatched roofs, wooden décor, and private pools, blending luxury with tropical simplicity. The resort’s seaside restaurant serves fresh seafood, authentic Thai dishes, and international cuisine, all accompanied by panoramic sea views.

 

Ao Kiu Nai remains the quietest area on Koh Samet, even during the high season. Visitors can read under the shade of trees or wander along the rocky shoreline revealed during low tide – a favorite spot for photographers. Ao Kiu Nok, meanwhile, is more open and lively, especially at sunset when travelers gather on the rocks to capture the last golden rays of the day.

 

The best time to visit Ao Kiu is between November and May, when the sea is calm and clear – perfect for swimming and snorkeling. From June to October, the rainy season brings occasional storms and limited boat services, but the quieter atmosphere offers an ideal escape for those seeking solitude. During the holiday season (New Year and Songkran), advance booking is highly recommended, especially at Paradee Resort, which often fills up months ahead.

 

Getting There: From Bangkok, drive about 2.5–3 hours to Rayong Province and head to Ban Phe Pier, where boats to Koh Samet depart regularly. Once you arrive at Na Nuan Pier on the island, take a local songthaew or taxi to Ao Kiu (about a 20-minute ride). The road is winding but scenic. Paradee Resort also provides private speedboat transfers, taking around 15 minutes from the mainland.

 

Although part of Ao Kiu is privately managed, visitors are welcome to explore the beach and rocky areas. The bay is under the protection of Khao Laem Ya–Mu Ko Samet National Park, which emphasizes conservation and eco-tourism. Travelers are encouraged to avoid littering, stepping on coral reefs, and using harmful sunscreens to help preserve this pristine environment.

 

Nearby attractions include Ao Wai (2 km away) with its colorful coral reefs, Ao Phrao (3 km away) on the island’s west coast for spectacular sunsets, Ao Phai (4 km away) known for beachfront cafés, and Ao Pakarang (1.5 km away), a great snorkeling spot reachable by kayak. Each bay offers its own unique view of Koh Samet’s charm.

 

Ao Kiu is more than just another beach – it is a symbol of quiet beauty and balance. It’s the perfect destination for those who want to connect with nature, enjoy both sunrise and sunset in one day, and find peace in the gentle rhythm of the waves under a sky full of stars.
