Casuarina Beach sits on Karaitivu island, connected to the Jaffna mainland by a causeway, and takes its name from the tall casuarina trees that line the sand. It is a long, gentle beach with shallow water, local families picnicking in the shade and very few foreign visitors. If you want a northern beach without the resort development of the south, this is it.
The appeal is not what is there but what is not: no beach bars, no sunbeds for hire, no one selling you a boat trip. Just trees, sand and a shallow sea.
The beach and the water
The water is calm enough for wading in the dry season, and the curve of the coast makes for good sunset walks. The sand is pale and the shelf is gentle, which suits children in calm weather.
There are no lifeguards and limited facilities, so bring water, snacks and shade. The beach is used by local families, especially at weekends, and it is worth dressing modestly and behaving respectfully away from the water.
Outside the dry season the north-east monsoon can bring wind, rain and rougher seas. Check conditions before you set out, and do not swim if the water looks unsettled.
Karainagar and the causeway
Karainagar itself is a quiet island with fishing villages, temples and a causeway that offers views across the lagoon. The drive from Jaffna takes about thirty to forty minutes, and a tuk-tuk or private car is the easiest way to get there.
The causeway crossing is part of the pleasure: shallow water, palmyra palms and small boats, with the Jaffna peninsula behind you. Stop if you can; it is a good place for photographs in the late afternoon.
Combine the beach with a stop at the Karainagar temple or a seafood lunch on the way back. The island has a few small shops but no proper restaurants, so plan around that.
Getting there without a car
Tuk-tuks are the easiest way to reach the beach, and a return trip should be arranged with the driver, including a pickup time. Mobile signal is patchy on the island, so do not rely on calling for a ride back.
Buses run from Jaffna to Karainagar, but they are infrequent and the walk from the stop to the beach is long. Unless you have time and patience, a tuk-tuk is worth the money.
If you are staying in Jaffna, a half-day trip is enough. Leave in the morning, swim and eat, and be back before dark.
A note on the north
The peninsula is still recovering from the civil war, and tourism here is thin. That is part of why it feels unspoiled, and also why facilities are basic.
Spending money locally — on tuk-tuks, food and small purchases — matters more here than in the resort south. Ask before photographing fishing boats or people, and dress a little more conservatively than you would on the south coast.
May to September is the dry, sunny season on the north coast. Outside that window, the northeast monsoon can bring wind and rain.
Is it worth the trip?
If you are in Jaffna for a few days, yes. It is a pleasant, unpolished beach and a glimpse of the peninsula beyond the town.
If you have only one day in the north, prioritise Jaffna Fort, Nallur Temple and the market. Casuarina is a bonus, not the main event.
For anyone who has done the south coast and found it too developed, the northern beaches are a quiet corrective. Bring a book and lower your expectations of service. It is a simple, unpolished beach — and that is exactly the point in the Northern Province.
