The main beach of Koh Kradan is the crown jewel of the Trang Sea islands. Stretching about 2 kilometers, it boasts powdery white sand and crystal-clear waters that let you see the seabed below. The peaceful vibe makes it perfect for relaxing, listening to the waves, watching the sunrise, or swimming along the shore. The snorkeling here is top-notch, with vibrant coral reefs teeming with clownfish, butterflyfish, and colorful staghorn coral—all just steps from the beach. Even beginners can enjoy the underwater world easily, thanks to the shallow, calm waters.

Located on the island’s western side, Ao Nieng is a hidden gem, mostly known among seasoned divers. The waters here are deep, clear, and ideal for scuba diving rather than snorkeling. It’s home to rare fish species and diverse coral formations. Getting there might require a bit of adventure—either a small boat ride or a trek through natural trails—but the scenic journey is well worth it. On lucky days, you might even spot dolphins or sea turtles swimming by.

Also known by locals as “Dream Beach,” Ao Phai is a quiet little bay on the southern part of the island. It’s far from the accommodations and lacks shops, so the nature here remains wonderfully untouched. It’s the perfect spot for those seeking solitude—ideal for meditating, reading, or sunbathing. The sand here is a slightly deeper cream color, and while the water gets deep quickly, it remains crystal clear. If you’re lucky, you might spot some hermit crabs casually strolling along the beach!

Situated on the island’s northwest coast, Ao Chong Lom is famed for offering the best sunset views on Koh Kradan. With cool breezes almost all day, it’s a lovely place for an evening picnic while watching the sky gradually change colors. From here, you can easily catch a boat to nearby islands like Koh Mook or Koh Ngai, making it a popular pit stop for one-day island-hopping trips.

Koh Mook is a dream destination for anyone wanting to experience the magic of the famous Emerald Cave (Tham Morakot). This natural sea cave has a narrow entrance accessible only by swimming through an 80-meter dark tunnel. During high tide, the water rises to the cave’s ceiling, so tours are usually timed during low tide or when water levels are safe. Inside, you’ll find a hidden beach surrounded by towering limestone cliffs. When sunlight streams through the cave’s entrance, it lights up the water in a stunning emerald green glow—mysterious, magical, and totally wow-worthy!

Not far from Koh Mook, Koh Chueak is a small, uninhabited island with no beach to land on—but it’s a snorkeler’s paradise. Surrounded by one of the most diverse and vibrant shallow coral reefs in Trang’s waters, the island is home to colorful marine life like damselfish, clownfish, butterflyfish, staghorn coral, mushroom coral, and brain coral. It's an ideal spot for beginners or families with kids, thanks to its shallow, calm waters and gentle currents.

Koh Waen may not be as well-known as other islands, but for scuba diving lovers, it’s a true hidden gem! With deepwater coral reefs and massive underwater rock formations, it’s home to many deep-sea species. The water here is cool and crystal clear—you might even spot lionfish, blacktip reef sharks, or stingrays depending on the season. Many divers rank Koh Waen as one of the top 5 dive spots in the southern Andaman Sea!

Small but charming, Koh Maa sits close to Koh Chueak and Koh Waen. Its highlight? Gorgeous turquoise waters that need no filter! The island’s crescent-shaped beach is paired with quirky rock formations that make it an Instagram favorite. If you’re into social media-worthy views, this is your spot. It's perfect for a lunch break and a refreshing swim before heading back.

Koh Ngai is one of the most popular islands in the Trang archipelago. A mid-sized island with plenty of accommodation and dining options, it’s a great place to stop and rest mid-trip. Its long beach runs alongside several resorts, and there are shallow coral reefs behind the island for easy snorkeling. After a dip in the sea, chill with a cool drink and enjoy a laid-back sunset view. Many one-day tours end their trip at this scenic and relaxing island.

Koh Kradan isn’t just about powdery white sands and crystal-clear waters. The island also offers plenty of awesome activities—whether you’re into adventure, relaxation, or just soaking up the natural vibes. Whether you're traveling solo, as a couple, or with a whole crew, there's something fun waiting for you!
