Introduction
Nestled off the pristine shores of Nilaveli in Trincomalee, Pigeon Island Marine National Park stands as one of Sri Lanka’s most spectacular underwater destinations. This protected marine sanctuary offers snorkellers an unforgettable glimpse into a thriving underwater ecosystem, where vibrant coral gardens meet crystal-clear turquoise waters.
Whether you’re a first-time snorkeller or an experienced ocean explorer, Pigeon Island promises an adventure that combines natural beauty, marine biodiversity, and sustainable tourism practices.
Why Pigeon Island is Special for Snorkelling
Unparalleled Marine Biodiversity
Pigeon Island Marine National Park is home to over 300 species of coral reef fish and 100 species of coral, making it one of the most biodiverse marine areas in Sri Lanka. The shallow reef systems surrounding the island create perfect conditions for snorkellers to observe:
- Blacktip reef sharks gliding gracefully through the shallows
- Green and Hawksbill sea turtles feeding on seagrass
- Schools of vibrant parrotfish, angelfish, and butterflyfish
- Clownfish (Nemo!) hiding among sea anemones
- Moray eels peeking from coral crevices
- Blue-spotted stingrays resting on sandy patches
Beginner-Friendly Shallow Reefs
Unlike many world-class snorkelling destinations that require deep diving or strong swimming skills, Pigeon Island’s reefs begin in waist-deep water. This makes it ideal for:
- Families with children
- First-time snorkellers
- Non-swimmers using life jackets
- Anyone nervous about deep water
The gradual depth increase means you can explore at your own pace, staying close to shore while still witnessing incredible marine life.
Protected Marine Environment
As Sri Lanka’s 17th marine national park (declared in 2003), Pigeon Island benefits from strict conservation measures. Fishing, coral damage, and pollution are prohibited, ensuring the ecosystem remains healthy and vibrant for future generations.
Best Time to Visit Pigeon Island for Snorkelling

While some operators still run trips during calmer days in this period, March to September remains the optimal window for snorkelling at Pigeon Island.
