    Ko Sam Phee Nong, or Three Brothers Island, is a reliable starter site in the Koh Rong Archipelago, especially if you're new to the area. It’s a shallow dive, topping out at 13 meters, which makes it perfect for knocking off some rust or getting comfortable in the water. We usually find plenty of small reef fish flitting amongst the patches of hard coral, and sometimes a grumpy stonefish blended into the rocks if you look close enough. It’s not going to blow your mind with pelagics, but for an easy, pleasant dive with decent visibility on a calm day, it’s a good shout.
