About Hin Ngam dive site

Hin Ngam is a sheltered bay complete with peaceful sand and an encircling fringing reef. Its depth ranges from 16 and 60 feet (5 to 18 meters), making it perfect for intermediate and beginners. Plus, its proximity to Aow Leuk only increases this destination’s popularity as one of the most sought-after snorkeling and diving sites around.

In fact, many dives start at Hin Ngam and continue to Aow Leuk.

Hin Ngam’s three towering pinnacles provide the perfect habitat for a plethora of marine life, including shrimps, turtles, porcupine pufferfish, scorpionfish, pipefish, white-eyed moray eels, and jenkins/blue-spotted rays.

At Hin Ngam, you can take on the thrilling challenge of exploring the majestic pinnacles scattered over the sand, or opt to leisurely cruise along its stunning coastline. Regardless of which journey you choose, this vista offers a delightful experience with its simple pleasures.

The remarkable coral reef is full of life, boasting a wide range of species including staghorn, brain, and star corals, as well as Christmas tree worms.

Submerged in the ocean, the bay is blanketed with sand but does not have a beach. Therefore, it’s more suitable for advanced divers to master their skills or rescue scenarios rather than open water diver training. Also, the sandy bottoms are often a little deeper than other dive sites like Aow Leuk.
