St Mary's Island from Udupi: Ferry, Basalt Columns and Day-Trip Plan

Six kilometres off the Karnataka coast, a small island rises out of the Arabian Sea made almost entirely of hexagonal rock columns — some standing in perfect honeycomb walls, others scattered like a giant's building blocks. St Mary's Island, off Malpe near Udupi, is India's most striking geological oddity you have probably never heard of: an 88-million-year-old volcanic formation that looks designed rather than erupted.

The geology: why the columns exist

The columns are basaltic lava formations — when thick lava flows cool and contract, they crack into polygonal columns, and here the geometry came out almost impossibly regular. The formations were declared a National Geological Monument by the Geological Survey of India in 1979. The group is actually four small islands, of which the northernmost carries the famous column formations.

The Portuguese landed here in 1498 and named it after Mary — locals also call it Coconut Island or Thonsepar. Outlook Traveller's St Mary's Island feature captures the surreal first sight of the columns rising from the surf.

The ferry: timings, tickets and the weather reality

The island is reached only by boat from Malpe Beach, a 25–30 minute ride. The boating office at Malpe operates daily from roughly 9 AM to 5 PM in season, and return tickets are inexpensive, with a reduced fare for children — cash and UPI both work at the counter, and online booking is rarely available, so arrive early on weekends to avoid the queue. Small boats carry 12–14 people, while larger ferries depart once they fill.

The hard truth: ferries run only from about September/October to May. During the monsoon (June to September) the sea is too rough and services are suspended entirely. Even in season, sailings are weather-dependent — if the sea is choppy, boats do not go. Check conditions at the jetty before making the drive, and keep a buffer plan for Udupi town.

What to do on the island (and what not to)

Plan for 60–90 minutes on the island itself. Walk the basalt columns — the rocks are sharp and slippery, so wear sandals or sneakers with grip, not thin flip-flops — then wander the shell beach, which is carpeted with broken shells rather than fine sand. Photography is the main activity: mid-morning to early afternoon gives the tealest water.

Now the important don'ts: this is not a swimming beach. Strong currents and jagged rock make swimming and diving off the rocks genuinely dangerous, and lifeguards enforce it. Carry your own snacks and water — there are limited stalls — take every wrapper back with you, and do not pocket shells or rock pieces.

Combining it with Udupi

St Mary's is a half-day; Udupi makes it a full one. Before the ferry, have breakfast in Udupi town — this is the birthplace of the Udupi restaurant empire, so the masala dosas and filter coffee are the real thing. After the island, visit the Sri Krishna Temple, Udupi's spiritual heart, and catch sunset at Kaup Beach with its century-old lighthouse.

Malpe Beach itself is the mainland hub for parasailing, banana rides and jet skis, if you want water sports the island cannot offer. The Hindu's report on the island's tourism pull notes that weekend and holiday footfall can double — so a weekday visit is calmer.

How to reach and best time

The nearest railway station is Udupi, on the Konkan line; Malpe Beach is 6–10 km away, a 15–30 minute auto or cab ride. Mangalore International Airport is about 60 km south. The best visiting window is October to January — pleasant weather, the clearest water colour and regular ferry schedules.

March to May is hot but the ferries still run; June to September, the island is effectively closed. A realistic plan: an inexpensive ferry ride, a short auto hop to Malpe, and 2.5–4 hours total including queues and island time.

A sample day-trip timeline

The island rewards an early start. Aim to reach Malpe jetty by 9:30–10 AM: buy your round-trip ticket, board the first or second ferry of the day, and you are on the island by 10:30. Spend the first hour at the basalt columns — morning light is the best photography, and the crowds thin out later — then swim and walk the southern cove. Pack a picnic or eat at the small snack shacks near the jetty side, and catch a return ferry by 1:30–2 PM, leaving the afternoon for Malpe beach itself and the Malpe fishing harbour, where the evening fish market is a spectacle in its own right.

Pair the trip with Udupi's other draws if you have the full day: the Shri Krishna Matha and its Kanakana Kindi, the old city's temple lanes, and a banana-bun-and-filter-coffee stop at one of the town's legendary old restaurants. Udupi is also the origin of the Udupi restaurant cuisine served across India — eating a temple-town meals plate here, in its birthplace, is the correct way to close the day. The Outlook Traveller feature on St Mary's Island frames the island as exactly this kind of half-day anchor within a wider Udupi–Malpe trip, which is how it works best in practice.

What to carry: water and snacks (the island has limited options), swimwear and a change of clothes, reef-safe sunscreen, a dry bag for your phone, and cash for the ferry tickets and small purchases. Wear footwear you can wade in — the landing is from the boat into shallow water in many conditions. The basalt rocks are sharp and slippery when wet, so take the column photographs from the stable platforms rather than climbing the formations; they are a protected geological monument, and chipping or defacing them is an offence. Leave no litter — the island's beauty is exactly as fragile as it looks.

Frequently Asked Questions

Can I swim at St Mary's Island?

No — and you should not try. Strong currents, submerged rocks and jagged basalt make the water around the island dangerous for swimming, and there are no lifeguards on the island. Use Malpe Beach on the mainland for water activities instead — it has the lifeguards, the shacks and the calm surf the island deliberately lacks.

What are the ferry timings to St Mary's Island?

Boats typically run from about 9 AM to 5 PM daily during the October–May season. Timings are weather-dependent; services are suspended in the monsoon and on rough-sea days.

How much does the St Mary's Island ferry cost?

Return tickets are bought at the boating counter at Malpe Beach, with a reduced fare for children. Confirm the current fare at the counter, as it varies slightly by season — and arrive early on weekends, when the first boats fill fast.

Is St Mary's Island open in the monsoon?

No. Ferry services are suspended from June to September when the Arabian Sea is rough, and the island is effectively inaccessible in those months. October to January is the best and most reliable window — the sea is calmest, the light is clearest for photographs, and cancellations are rare.

How much time do I need for the trip?

Budget 2.5–4 hours: the queue and ticket purchase, the 25–30 minute boat ride each way, and 60–90 minutes on the island. Pair it with Udupi town for a full day.
