StandoutExceptional marine biodiversity

Beacon Reef is one of those easy Similan dives, perfect for getting back into the swing of things. It’s a shallow spot, topping out around 21 metres, which means plenty of bottom time. We usually find it fairly protected from the stronger currents that sometimes whip through the Similans, making it a great choice for newer divers or anyone keen on a relaxed drift. You’ll typically see plenty of reef fish flitting between the corals, sometimes a turtle munching away, and if you look closely, smaller critters tucked into the nooks. It’s not flashy, but it’s consistently pleasant, a solid option when you just want to enjoy being underwater.
