Thonglang Beach in Chonburi is one of the charming beaches located on Koh Larn. It sits just north of the busy Tawaen Beach, separated by a rocky headland. Although the two beaches are close to each other, Thonglang has its own entrance route, making it quieter and more distinct. This separation allows Thonglang to maintain its own character still lively with group tours, but less crowded than its popular neighbor. It’s a great choice for travelers who want a lively seaside vibe without overwhelming crowds.

 

Thonglang Beach stretches for about 250–500 meters, depending on how you measure the sandy area versus rocky sections. The seawater here is clear, calm, and gradually sloping, making it suitable for safe swimming in many spots. Some sections of the shore are dotted with rocks alongside fine white sand, creating a natural beauty unique among Koh Larn’s beaches. With fewer people, visitors can relax on beach chairs, sunbathe, or simply stroll along the sand without feeling rushed.

 

There are plenty of water activities to enjoy at Thonglang. Jet skiing, banana boats, and glass-bottom boats that showcase the underwater world are all popular options. Kayaks are also available for those seeking a more peaceful way to explore. Snorkeling near the rocky areas is another highlight, as the clear water reveals coral and diverse marine life close to shore.

 

One of the hidden gems here is Tham Daeng, or the Red Cave—a small sea cave tucked away at the edge of the beach. Access depends on the tides, which makes it feel like a secret spot. It’s a favorite place for photography, offering a unique backdrop that sets Thonglang apart from other Koh Larn beaches.

 

Facilities around the beach are convenient enough for day-trippers. Fresh seafood restaurants, small local shops, and rows of umbrellas with sun loungers line the beach. Nearby resorts and guesthouses also welcome visitors who wish to stay overnight, making it easy to catch the stunning sunset or enjoy the tranquil morning by the sea.

 

Reaching Thonglang Beach can be done in several ways. From Pattaya, travelers usually take a ferry or speedboat to Koh Larn, then continue by songthaew or motorbike taxi to the beach entrance. There’s also a walkway that connects from Tawaen Beach, though it’s not in perfect condition in some parts. Still, the walk offers scenic views of the sea along the way.

 

Overall, Thonglang Beach offers the perfect balance between energy and peace. It’s ideal for families, groups of friends, or solo travelers looking for a less-crowded but still lively alternative to the island’s busiest beaches. With its clear waters, range of activities, and natural highlights like the Red Cave, Thonglang deserves a spot on any itinerary for Koh Larn in Chonburi.
