Sri Lanka, an island nation in the Indian Ocean, is celebrated for its lush landscapes, ancient heritage, and remarkable biodiversity. Its national parks, such as Yala, Wilpattu, and Udawalawe, are home to iconic wildlife including Asian elephants, leopards, sloth bears, and spotted deer. The island’s rainforests shelter rare species like the purple-faced langur and the Sri Lankan blue magpie, while its wetlands and lagoons attract flamingos, pelicans, and many migratory birds. Along the coast, sea turtles nest on sandy beaches and blue whales roam offshore waters. With rich ecosystems packed into a relatively small area, Sri Lanka is recognized as one of the world’s top wildlife destinations
Visa
To enter Sri Lanka, you need to apply for an ‘Electronic Travel Authorization’ (ETA) which is a form of visa.
Applying for an Electronic Travel Authorization (ETA)
Apply for a Sri Lanka ‘Electronic Travel Authorization’ (ETA) online. You should do this before travel. ETAs will be valid for 30 days. Alternatively, you can also apply for an on-arrival ETA at the airport’s Immigration counter.
If you plan to stay longer, you can apply for an extension online through Sri Lankas official Immigration portal. You do not need a visa if you are transiting through Sri Lanka by air, if the connecting flight is within 24 hours of your arrival. Check with your airlines about transit times.
For more information on Sri Lankan visas, please visit Department of Immigration and Emigration.
Overstaying your visa
If you overstay the period of your ETA (30 days), you risk being subject to immigration procedures that may include temporary detention, a fine, deportation at your own expense, a travel ban or refusal of entry to Sri Lanka in the future.
