Have you ever dreamed of escaping to a tropical paradise, where crystal-clear waters lap against pristine white-sand beaches, and vibrant coral reefs teem with marine life? Look no further than Koh Larn, also known as Coral Island, a hidden gem just a short ferry ride from the bustling city of Pattaya, Thailand. This small yet stunning island in the Gulf of Thailand offers a perfect blend of relaxation and adventure, making it an ideal destination for travelers seeking a day trip or a quick getaway from Pattaya or Bangkok.
Koh Larn is a compact island, measuring approximately 4 kilometers long and 2 kilometers wide, but don’t let its size fool you—it’s packed with natural beauty and exciting activities. The island is famous for its six main beaches, each offering a distinct vibe. Tawaen Beach, the most popular among visitors, buzzes with energy, featuring water sports like jet skiing and banana boat rides, alongside beachside restaurants serving fresh seafood. If you prefer a quieter escape, head to Tien Beach or Samae Beach, where you can unwind under swaying palm trees, listen to the gentle waves, and enjoy a more serene atmosphere.

Exploring Koh Larn’s Underwater Wonders
One of the standout attractions of Koh Larn is its namesake coral reefs, which draw snorkelers and scuba divers from around the world. These vibrant underwater ecosystems are home to a dazzling array of marine life, including colorful tropical fish, sea turtles, and even small reef sharks. Whether you’re an experienced diver or a first-time snorkeler, the clear waters around Koh Larn provide an unforgettable glimpse into Thailand’s aquatic treasures. For those who’d rather stay dry, glass-bottom boat tours offer a fantastic alternative, letting you marvel at the coral and fish without getting wet.
Beyond the Beaches: Activities for Everyone
Koh Larn isn’t just about its beaches and reefs—there’s plenty to explore on land too. Rent a bicycle or take a leisurely walk to discover the island’s interior, where lush greenery and scenic hiking trails await. One must-visit spot is the Big Buddha statue, perched on a hilltop with sweeping panoramic views of the island and the sparkling Gulf of Thailand. It’s a peaceful spot to take in the scenery and snap some photos. For a taste of local life, visit the small fishing village on the island, where you can watch fishermen at work and enjoy authentic Thai seafood dishes at quaint eateries.
If you’re craving more action, Tawaen Beach has you covered with thrilling options like parasailing, where you can soar above the coastline and take in breathtaking aerial views. For a laid-back day, simply rent a beach chair and umbrella, sip on a refreshing coconut, and let the tropical vibes wash over you.
How to Get to Koh Larn
Getting to Koh Larn is a breeze, making it an accessible escape from Pattaya. Ferries depart regularly from Bali Hai Pier, with the ride taking about 45 minutes—a relaxing journey with scenic sea views. If you’re short on time, opt for a speedboat, which zips across the water in just 15 minutes. Once you arrive, getting around is easy. You can explore on foot, rent a bicycle, or hop on a motorbike taxi. Songthaews, shared taxis that follow the island’s main routes, are another convenient option.
While Koh Larn offers accommodations ranging from budget guesthouses to mid-range resorts, most visitors treat it as a day trip from Pattaya or even Bangkok, returning to the mainland by evening.
