Matara and Dondra Head

Matara sits where the Nilwala Ganga meets the sea, and the Dutch built a fort here in the seventeenth century to control both. The main fort's ramparts still enclose a chunk of the old town, and you can walk them past churches, colonial houses and the lighthouse at the river mouth in about half an hour.

The more curious structure is the Star Fort, built in the 1760s after a local uprising overran the main fort. It is a small hexagonal outwork with a moat, a drawbridge and a Dutch coat of arms over the gate, sitting oddly in a modern roundabout. It takes fifteen minutes to see and it is one of the more charming pieces of colonial architecture on the coast.

Polhena, on the western edge of Matara, is the reason most travellers stop. A fringing reef runs parallel to the shore and creates a shallow lagoon behind it where the water stays calm even when the open sea is choppy. It is one of the few places on the south coast where you can snorkel straight off the beach.

Green turtles feed on the seagrass inside the lagoon and are seen regularly, often within a few metres of waders. Watch them from a distance, do not touch, chase or ride them, and refuse any offer to hand-feed one for a photograph, which is common along this coast and harmful to the animals. Coral inside the lagoon is patchy, so expect fish and turtles rather than a spectacular reef.

Dondra Head, about 6 kilometres east of Matara, is the southernmost point of Sri Lanka, and the next land directly south is Antarctica. The point is marked by Dondra lighthouse, an imperial-era tower of around 49 metres, the tallest in the country and one of the tallest in South Asia. It is a working light, and access inside depends on the keepers.

The headland matters for more than geography. The continental shelf drops away sharply just south of here, which is precisely why the blue whales gather within reach of Mirissa's boats. Standing on the point, you are looking at the same deep water the whale boats work at dawn.

The village at Dondra is properly called Devinuwara, the city of gods, and it holds a temple to Vishnu that was once among the grandest religious complexes in the country before the Portuguese destroyed it in 1588. The rebuilt Devinuwara Devalaya remains an important shrine, and its annual Esala festival in July or August brings a perahera with dancers, drummers and a large local crowd.

It is a genuinely local festival rather than a tourist event, which makes it more rewarding and requires more care: dress modestly, ask before photographing, and follow the lead of the people around you.

Matara follows the south coast calendar: roughly November to April, with December to March most reliable. That is when Polhena's lagoon is clear and calm enough to snorkel, and when the coast road is at its most pleasant.

From May to September the south-west monsoon brings rain and rough seas. The lagoon at Polhena is more sheltered than most beaches on this coast, but visibility drops and swimming outside the reef becomes unsafe. The town itself is perfectly visitable year-round.

Matara is roughly two and a half hours from Colombo on the southern expressway, and about 45 minutes east of Mirissa on the coast road. It is the southern terminus of the coastal railway line, which makes the train from Colombo a genuinely pleasant approach, particularly the final stretch along the sea.

Most visitors base themselves at Mirissa or Weligama and come to Matara for a half day, which is a sensible approach given the accommodation is better there. If you want to snorkel Polhena regularly, the small guesthouses on that beach are the better choice.

The efficient shape is Polhena first thing for snorkelling while the water is calm and clear, the Star Fort and the ramparts mid-morning, then Dondra Head and the lighthouse before lunch. That gets you the best of both the sea and the heritage without fighting the afternoon heat.

Lankan Stays & Trails builds Matara into south coast itineraries as a morning between Mirissa and Tangalle, which is where it naturally belongs geographically and where it makes most sense in a day's driving.
