Chedi Rock, or Hua Chedi Koh Ngam Yai, is a pretty straightforward dive for the Gulf. It’s shallow, only topping out at 14m, which makes it a good spot for newer divers or those looking for an easy second dive. The main feature is a series of rocky outcrops, covered in a mix of hard and soft corals. We’ve seen plenty of reef fish here – things like butterflyfish and angelfish are common – and if you’re patient, you might spot a turtle cruising by.
