Strict Swimming Prohibition & Island Code
Submerged Rock Hazard: Swimming around St. Mary's Island is strictly forbidden by the district administration. The island is encircled by razor-sharp submerged basalt prisms, treacherous crevices, and strong open-sea undertows.
Plastic-Free Sanctuary: St. Mary's Island is a strict zero-plastic zone. All disposable plastic bags, packaging, and non-biodegradable items are confiscated at the Malpe boarding checkpoint. Overnight camping is not permitted; the last return ferry departs at 05:00 PM.
1. Coastal Character & Volcanic Origin
St. Mary's Island, locally referred to as Thonsepar and Coconut Island, is an uninhabited geological wonderland situated approximately 6 kilometers offshore from Malpe port in Karnataka's coastal district of Udupi. Declared a National Geological Monument by the Geological Survey of India (GSI) in 1979, the island is internationally celebrated for its spectacular outcrops of columnar basaltic lava—monumental vertical pillars of rock sculpted naturally into polygonal and hexagonal geometric columns that rise like gigantic church organ pipes out of the turquoise waters of the Arabian Sea.
Scientific petrological studies confirm that these columnar rhyodacites and basalts were created approximately 88 million years ago during the late Cretaceous period. When the Indian tectonic plate was rifting away from Madagascar over the Marion volcanic mantle plume, massive sub-aerial lava flows cooled slowly and uniformly in the atmosphere. The resulting thermal contraction created regular vertical fracture planes, producing geometric hexagonal pillars identical in geological genesis to Northern Ireland's famous Giant's Causeway.
The St. Mary's Archipelago (Oithakkal Group)
The protected island cluster consists of four distinct rocky islets:
1. Coconut Island (North Island)
The largest island (approx. 500m long), featuring the most iconic columnar basalt cliffs, a crown of coconut palms, shaded wooden gazebos, and the tourist ferry landing.
2. North Island & South Island
Rugged rocky outcrops showcasing horizontal and radiating columnar jointing where basalt pillars fan out like stone wagon wheels.
3. Daryabahadurgarh Islet
The southernmost islet situated near the Malpe port entrance, featuring an ancient elevated stone watchtower built by the Keladi Nayakas.
2. History: Vasco da Gama 1498 Landfall
Historical tradition links St. Mary's Island with the dawn of the Age of Discovery in the Indian Ocean. In May 1498, after navigating the uncharted waters of the Arabian Sea from Mozambique, the Portuguese navigator Vasco da Gama made a temporary landfall on this uninhabited rocky island before proceeding south to Kozhikode (Calicut).
According to Portuguese maritime logs, da Gama erected a stone cross (padrão) on the island's highest basalt promontory and dedicated the land to Mother Mary under the title O Padrão de Santa Maria, which gave the island its enduring international name.
3. Seashell Beach & Marine Ecology
The western and northern shorelines of St. Mary's Island are unique on the Indian mainland for their composition: instead of standard quartz sand, the beach foreshore consists of a thick, crunchy carpet of millions of naturally polished whole sea shells, cowries, clam shells, and coral fragments accumulated by ocean currents.
The crystal-clear intertidal lagoons surrounding the basalt columns are populated by colorful reef fishes, hermit crabs, sea anemones, and rock oysters. Soaring above the island's coconut canopy, White-bellied sea eagles (Haliaeetus leucogaster) and Brahminy kites nest in the rocky cliff crevices, using the basalt pillars as observation perches for hunting fish in the shallow sea.
4. Visitor Experience & Ferry Transit Logistics
Visiting St. Mary's Island is an exhilarating half-day coastal excursion:
- Malpe Sea Walk & Ferry Jetty: Tourist ferries depart regularly from the Malpe Sea Walk Jetty and Malpe Main Beach. The 20-minute boat ride offers views of the Malpe fishing harbor and passing wooden trawlers.
- Island Boardwalks & Photography: Paved pathways, timber bridges, and designated viewpoints allow visitors to traverse the island and photograph the hexagonal basalt pillars safely without climbing on hazardous wet rocks.
- Operating Season: Ferries operate daily between October 1 and May 31 from 09:00 AM to 05:00 PM. Ferry operations are completely suspended during the monsoon season (June to September) for marine safety.
District & Pilgrim Hub: St. Mary's Island is located in Udupi District. It pairs naturally with the famous 13th-century Udupi Sri Krishna Matha (10 km east), the water sports haven of Malpe Beach, the bioluminescent shores of Mattu Beach (15 km south), and the coastal cliff shrine of Kaup (Kapu) Lighthouse Beach (22 km).

7. Frequently Asked Questions
The basalt pillars formed 88 million years ago when sub-aerial volcanic lava erupted during the rifting of India from Madagascar. Uniform cooling caused the dense lava to contract into vertical hexagonal and pentagonal rock columns.
No, swimming is strictly prohibited around the island due to sharp submerged basalt rocks, strong ocean currents, and deep trenches.
A small government kiosk provides packaged drinking water and light refreshments, but visitors are advised to carry their own reusable water bottles. Disposable plastic packaging is strictly prohibited.
The ferry ride across the Arabian Sea takes approximately 20 to 25 minutes each way from the Malpe Sea Walk Jetty.
