Ao Thong Yi

Open Days: Daily

Opening Hours: 24 Hours

 

Ao Thong Yi, also known as Thong Yi Bay, is a quiet natural bay in Khanom District, Nakhon Si Thammarat Province. Located south of Nai Phlao Beach, it is considered one of the southernmost coastal attractions of Khanom’s seaside route. The bay is surrounded by Khao Phlao and Khao Klang, giving it a peaceful and private atmosphere. Its beach combines soft sand, rocky outcrops, clear water, coastal forest, and a mountain backdrop, making it suitable for seaside rest, photography, swimming in calm conditions, fishing, shallow snorkeling, and camping in permitted areas.

 

Ao Thong Yi is different from the busier parts of Khanom such as Na Dan Beach, Khanom Beach, or Nai Phlao Beach. It feels more secluded and natural. Visitors come here for quiet scenery rather than crowds, shops, or large-scale beach entertainment. The bay is ideal for travelers who want a slow coastal experience, sea breeze, a peaceful shoreline, and a strong sense of nature.

 

The surrounding area belongs to Khanom’s diverse coastal landscape, which includes mountains, foothills, coastal plains, mangrove areas, streams, beaches, and bays. Khao Phlao, Khao Phlai Dam, Khao Pret, and other nearby hills form an important natural backdrop. This means Ao Thong Yi is not only a beach, but also part of a wider landscape where forested hills meet the Gulf of Thailand.

 

The beach at Ao Thong Yi alternates between sandy sections and rocky areas. Some parts are suitable for walking and resting, while other parts are better for photography and scenic viewing. Visitors should choose safe sandy areas for entering the water and avoid rocky sections during rough waves. The natural beauty of the bay comes from the balance between beach, rock, forest, mountain, and sea.

 

The southern side of the bay has coral reef areas and abundant fish, making it attractive for shallow snorkeling when sea conditions are calm. Snorkeling should be done carefully and responsibly. Visitors should not step on coral, touch marine animals, feed fish, or use the reef area carelessly. If planning water activities, it is safer to ask local operators or accommodation staff about the best timing and safe areas.

 

Ao Thong Yi is also known for camping. Its quiet atmosphere makes it suitable for visitors who want to sleep close to nature. However, camping should be done only in areas with permission or clear management. Visitors should not set up tents freely on the beach or near natural forest without approval. Thongyee Camping is one of the local operators associated with the beach area, offering accommodation, food, drinks, and some sea-related activities.

 

The bay is connected with several natural routes. From Ao Thong Yi, visitors can continue toward Ao Thong Yang and Khao Phlai Dam, or return to Nai Phlao Beach, Khanom town, and the main Khanom beach route. This makes it a good stop for travelers who enjoy coastal driving, hill views, hidden bays, and quieter beach landscapes.

 

Recommended activities include beach walking, resting by the sea, photographing rocks and mountains, swimming when the sea is calm, fishing in suitable areas, shallow snorkeling near the southern reef area, camping in permitted zones, and short nature walks along safe routes. Ao Thong Yi is best enjoyed slowly because its main value is its natural atmosphere rather than intensive activities.

 

The best time to visit is in the morning or late afternoon. Morning offers soft light, calmer beach conditions, and good photography opportunities. Late afternoon is suitable for resting, sea breeze, and a quieter coastal mood. Visitors who plan to camp should check weather conditions, prepare essentials, and use managed camping areas.

 

Getting There from Nakhon Si Thammarat city is easiest by private car or rental car. Take Highway 401 toward Khanom. At Khlong Leng Junction, marked by a dolphin statue, turn onto Highway 4014 toward Khanom town. At the main market intersection, continue to the coastal road, turn right along the beach road, and drive toward Nai Phlao Beach. At the Nai Pret junction, turn left toward Nai Phlao Beach and continue to the end of the concrete road to reach Ao Thong Yi.

 

The final approach to the bay uses local roads near hills and coastal terrain. Drivers should be careful, especially during rain, wet-road conditions, or late evening. First-time visitors should use navigation together with local advice. It is also practical to buy supplies in Khanom town before entering the bay area because shops and services at the far end are limited compared with the main beach zones.

 

Visitors should prepare drinking water, light food, sun protection, beach footwear or anti-slip shoes, a rubbish bag, a flashlight, insect protection, and spare clothes if swimming. Snorkeling equipment should be appropriate and used only when sea conditions are safe. Do not snorkel alone or enter the water during rough waves.

 

Responsible behavior is important. Visitors should keep the beach clean, avoid littering, avoid collecting coral or shells, avoid disturbing marine life, avoid loud noise, avoid making fires outside permitted areas, and respect private accommodation or managed camping zones. The bay remains special because of its quiet and natural character.

 

A practical one-day route can begin at Nai Phlao Beach, continue to Ao Thong Yi, then proceed to Khao Phlai Dam or Ao Thong Yang before returning to Khanom town for seafood or accommodation. This route gives visitors a complete view of Khanom’s coast: main beach, hidden bay, mountain-backed coast, viewpoint, and natural seaside atmosphere.

 

Overall, Ao Thong Yi is one of the most peaceful coastal destinations in Khanom. Its key features are its southern location, the surrounding mountains of Khao Phlao and Khao Klang, sandy-and-rocky beach, southern coral reef, abundant fish, camping atmosphere, and connection with Khao Phlai Dam and Ao Thong Yang. For travelers looking for a quieter and more natural side of Khanom, Ao Thong Yi is a meaningful coastal stop.
