Quick answer
Sri Lanka's offshore islands include Pigeon Island Marine National Park off Trincomalee (superb coral snorkelling with reef fish and harmless blacktip reef sharks), and the cluster of islands off the Jaffna peninsula in the north—Delft (Neduntheevu), with its wild ponies, baobabs, and coral-walled lanes; Nainativu, home to important Hindu and Buddhist shrines; and Karainagar with its fort and beach. There are also small southern islets like Taprobane near Weligama. Most are reached by short boat or ferry rides and offer a remote, distinctive change of pace.
Key takeaways
- Pigeon Island (Trincomalee) is the top island for reef snorkelling.
- The Jaffna islands—Delft, Nainativu, Karainagar—are remote and characterful.
- Delft has wild ponies, baobabs, and coral-walled lanes.
- Nainativu holds important Hindu and Buddhist shrines.
- Most are reached by short boat or ferry rides.
Pigeon Island
Off Nilaveli near Trincomalee, Pigeon Island Marine National Park is the island for marine life—a short boat ride to shallow coral gardens teeming with reef fish, turtles, and harmless blacktip reef sharks cruising the shallows. It's one of Sri Lanka's best and most accessible snorkelling spots, best in the east-coast season (roughly May to September).
The park limits numbers to protect the reef, so go early and tread (and swim) lightly.
The Jaffna islands
Off the far-northern Jaffna peninsula lies a cluster of low, sun-baked islands, reached by causeways and ferries. Delft (Neduntheevu) is the most striking—home to semi-wild ponies descended from colonial stock, baobab trees, a coral-stone Dutch fort, and lanes walled with coral. Nainativu (Nagadeepa) holds a revered Hindu kovil and an important Buddhist temple side by side, while Karainagar has a fort and quiet beach.
These islands feel like the edge of the country, steeped in Tamil culture and remoteness.

Southern & other islets
Elsewhere, tiny Taprobane Island off Weligama on the south coast is a private islet with a famous villa, glimpsed from the shore, while small islands dot the lagoons of the east and northwest. Boat trips from various coasts reveal sandbanks, bird islands, and fishing islets.
These add quirky variety for travellers who like discovering the unusual.
Visiting the islands
Pigeon Island is an easy half-day from a Trincomalee base in the east-coast season. The Jaffna islands are reached on day trips from Jaffna by ferry and causeway, best combined with exploring the peninsula's culture and cuisine. Check ferry times, take sun protection and water, and respect the islands' lived-in, sacred, and fragile-natural character.
These are detours for the curious rather than polished resort destinations.
Planning island detours
Fold Pigeon Island into an east-coast leg and the Jaffna islands into a northern one, both for travellers wanting to go beyond the standard circuit. A guide and a driver smooth the ferries and logistics.
