The Dive Site: Topography & What to Expect
Blue Lagoon is a small, protected bay. The dive typically starts on a shallow, sloping sandy bottom at around 5-10 meters, which is dotted with large coral bommies and artificial reef structures. This 'Aquarium' area is where most snorkelers and training dives happen. It's a fantastic, bright area to acclimatize and check your gear.
As you head deeper and away from the bay's centre, the bottom slopes gently to around 20-22 meters, where it meets a short, rich coral wall. The reef is a healthy mix of hard and soft corals, with myriad anemones and their resident clownfish. The combination of sand, coral heads, and a wall in one dive makes it diverse and interesting.
Marine Life: A 'Fish Soup' Experience
Divers and snorkelers love Blue Lagoon for its sheer density of life. It's not uncommon to spot several green turtles on a single dive, munching on sponges or resting on the coral. Look closely in the crevices for moray eels (zebra, snowflake, and giant), ribbon eels, and lionfish.
The sandy patches are home to camouflaged creatures like crocodilefish and bluespotted stingrays. You'll be surrounded by schools of surgeonfish, damselfish, and angelfish. For macro lovers, nudibranchs, cuttlefish, and octopus are common finds. While rare, whitetip reef sharks sometimes pass by in the deeper sections.
Conditions, Safety, and Suitability
This site is famous for being beginner-friendly. Currents are *usually* light, and the bay is protected from major swell. However, conditions can change. A mild downward current (down-current) can occasionally appear near the wall, which is why diving with an experienced local guide is essential. They will read the water and adjust the dive plan accordingly.
Visibility is typically good (15-25m) but can drop after heavy rain. Due to its popularity with snorkel tours, boat traffic can be high, especially mid-day. For this reason, always deploy a Surface Marker Buoy (SMB) before ascending and listen carefully to your guide's briefing.
