The Archipelago Island (also known as Helicopter Island or Dilumacad Island) in El Nido, Palawan, is a stunning naturally ring-shaped island famous for its dramatic limestone rock formation featuring a large hole through the island. This natural arch, carved by centuries of wave erosion, creates a breathtaking “hole-through” effect against the turquoise sea, making it one of the Philippines’ most photographed natural wonders.
How Was This Natural Hole-Through Formation Created?
Palawan’s iconic karst limestone landscapes, shaped over millions of years, are the result of tectonic activity, dissolution by rainwater, and relentless sea erosion. The massive hole in Archipelago Island formed as waves crashed against the softer sections of the cliff, gradually tunneling through the rock to create a perfect arch. From certain angles, the island appears almost ring-shaped, with the sea visible through the massive opening a true testament to nature’s sculpting power.
Similar formations dot the Bacuit Archipelago, but this one stands out for its size and dramatic silhouette, often resembling a helicopter from afar hence its nickname.
