Twin Rocks

Twin Rocks (El Nido)

Prepare for an unforgettable intermediate dive at Twin Rocks, a captivating dive site nestled on Miniloc Island's north side in El Nido. This site is renowned for its unique topography, featuring two prominent limestone outcrops rising from a sandy seabed, riddled with natural caverns and exciting swim-throughs. Divers will find a maximum depth of 30 m, with the sandy channel between the rocks typically around 16 m.

Diving Conditions & Certification

The water temperature at Twin Rocks generally ranges from a comfortable 24°C to 30°C, with cooler temperatures (24-26°C) observed between December and March, and warmer conditions (26-30°C) from April to November. While the current is often mild, it can become variable and occasionally strong, particularly around the full moon cycle. We recommend an Open Water certification for this dive site, though an Advanced Open Water certification is highly recommended on days with stronger currents to navigate the conditions and explore deeper areas more comfortably.

Marine Life Encounters

Twin Rocks is a vibrant hub of marine biodiversity. The sandy channel between the rocks is affectionately known by locals as "Stingray Airport," a fitting nickname given the numerous Blue-spotted Ribbontail Rays (Taeniura lymma) that divers can encounter. These rays, easily identified by their striking electric blue spots on a yellowish body and blue stripes on their tail, are nocturnal and often found resting under overhangs, table corals, or in caves during the day.

As you explore the rock formations, divers will be treated to a rich tapestry of table corals, sea whips, and sponges, which attract a variety of schooling fish. Keep an eye out for impressive schools of Giant Trevally (Caranx ignobilis), powerful predators that can grow over a meter in length and are often seen making rapid passes through smaller fish schools. Large Great Barracuda (Sphyraena barracuda) also frequent the area, adding to the thrill of the dive.

For macro enthusiasts, Twin Rocks offers delightful discoveries. We often spot the elusive Ornate Ghost Pipefish (Solenostomus paradoxus), masters of camouflage that blend seamlessly with crinoids, soft corals, and hydroids. These fascinating creatures are typically found in coral reefs between 3 m and 25 m deep and are especially prevalent during the breeding season, which generally aligns with the months of November to April. Another incredible find is the vibrant Peacock Mantis Shrimp (Odontodactylus scyllarus), known for its complex vision and powerful strike. These colorful crustaceans typically inhabit burrows in sandy or coral rubble areas, most abundantly between 10 m and 20 m.

Other notable residents include the majestic Bumphead Parrotfish (Bolbometopon muricatum), the largest species of parrotfish, which can grow up to 1.5 m and are often seen in herds grazing on coral. Divers may also spot the impressive Giant Moray (Gymnothorax javanicus) peering from crevices and the graceful Green Sea Turtle (Chelonia mydas) gliding through the waters.

Potential Hazards

While Twin Rocks offers an incredible experience, divers should be aware of potential hazards including variable currents, which can intensify, especially around the moon cycle. The presence of caverns and swim-throughs means there are overhead environments that require appropriate training and caution. Additionally, boat traffic in the area necessitates vigilance during ascents and descents.
