    StandoutExceptional marine biodiversity

    Meridian Beach offers a straightforward dive, perfect for those new to the Similans or knocking out a skills session. The sandy bottom slopes gently to about 10 meters, making it an easy drift along the beach. You’ll spot the usual suspects here: small reef fish, maybe a cuttlefish tucked into the sand, and we’ve even seen a few garden eels popping their heads out. It’s a nice, relaxed spot for checking your buoyancy or just getting comfortable in the water.
