St Mary’s Islands in Mangalore, Karnataka, lies a hidden geological wonder: St. Mary’s Islands. These islands are a breathtaking spectacle, distinguished by their unique hexagonal columnar basaltic rock formations.

These spectacular rock columns are a testament to a pivotal moment in Earth’s history. Geologists believe they were formed by sub-volcanic activity millions of years ago, a direct result of the monumental event when Madagascar drifted away from the Indian subcontinent.

Today, St. Mary’s Islands stand as a natural monument, offering visitors a rare glimpse into our planet’s ancient past, all set against a backdrop of the pristine Arabian Sea. It’s a truly fascinating destination where geology, history, and natural beauty converge.
