    StandoutExceptional marine biodiversity

    The Similans offer some decent snorkeling around the main islands. You’ll typically find shallow coral patches mixed with areas of seagrass, a good spot to look for flathead snapping shrimp or perhaps a Lattice monocle bream. It’s a straightforward area for beginners and a nice way to spend a surface interval if you’re diving. The visibility usually holds up well, making for easy viewing.
