Sri Lanka is a medium-risk country with moderate crime rates. Most travelers do not feel unsafe in the country. However, you should always be cautious while you are there. Crimes that tourists are most likely to encounter are pickpocketing and bag snatching, both of which are fairly common in Sri Lanka.
In addition to this, solo female travelers are at risk of sexual violence, which is why we always recommend choosing a group tour rather than exploring the country alone.
