    Koh Hong: Discover Krabi's Hidden Emerald Lagoon

    Koh Hong translates to “Emerald Island,” and the name is perfectly apt. This island features a completely enclosed freshwater lagoon surrounded by dramatic limestone cliffs—a natural wonder that seems almost mythical.

    The experience of paddling through the narrow coral passage into the lagoon and finding yourself surrounded by 200-meter cliff faces with no exit visible is surreal. You’ve entered a hidden world.

    Why Koh Hong?

    Image

    The Magical Lagoon

    The lagoon is the heart of Koh Hong’s appeal. It’s freshwater, enclosed by coral formations and limestone cliffs, and creates a sense of being in a secret place. The water is incredibly calm and peaceful.

    Paddling into the lagoon is an adventure in itself. You navigate through a narrow passage in the coral reef, and suddenly you’re in this enclosed world with the sky above and cliffs surrounding you.

    Dramatic Natural Setting

    The limestone cliffs rising around the lagoon create an almost otherworldly setting. The rock formations show geological patterns and colors—striations, vegetation, natural weathering patterns.

    It’s one of the most visually dramatic locations in Krabi.

    Snorkeling and Marine Life

    The coral passage and outer reefs host diverse marine life. Snorkeling here reveals healthy coral ecosystems and colorful fish.

    Unique Experience

    Koh Hong offers an experience you can’t get anywhere else. It’s not just a beach; it’s an enclosed natural wonder that creates a sense of discovery and adventure.

    What You'll Experience

    The Paddle Through the Coral Passage

    This is the signature Koh Hong experience. You’ll paddle (or be paddled on a canoe) through the narrow coral passage. It’s not dangerous, but it is thrilling—the passage is shallow and narrow, creating a sense of entering a hidden realm.

    What You'll Experience

    Time in the Lagoon

    Once inside the lagoon, time feels different. The cliffs rise around you. The water is still and reflective. You can swim, float, or simply sit and absorb the surreal beauty.

    Outer Reef Snorkeling

    Outside the lagoon, you’ll snorkel the outer reefs where marine life is abundant.

    World class scenery - excellent crew

    A truly amazing day with my beautiful family. I would happily say that this is a must do experience if you have a few days in Phuket. The scenery above and below the water line is absolutely stunning. Sara and crew were amazing people always making sure you were hydrated, fed and safe. They honestly could not have been more helpful.

    Sunrise in PhiPhi!

    Sara and her team were so phenomenal. Our driver was right on time at 5am with a big smile. The whole day was filled with snacks - they fed us so well! My husband and I could not swim but Sara and her team found ways to enhance our experience nonetheless. The views were spectacular and the beaches were stunning. The Thai sun favoured us for sure and we had nothing but the best experience. Thank you Sara and your whole team for the best ending to our trip :) khàawp khun khâ!!! With love from Canada xoxo
