Is it safe to travel to sri lanka?

Check on the US Emby website for a list of locations that the US says are not safe. That should give you an idea, but it is not always right. There has been a lot of civil war in Sri Lanka this last year, so that would be a concern. Check the CDC website for food/water/disease concerns. Also check the Sri Lankan Emby website for travel tips and visa requirements. If you have a good plan, that's your best bet. Google the latest news articles on what's going on in the country. Do as much research as you can. Also, try to find people who have been there and have done the same thing you want to do. Research, plan. That's my advice.
