Kiribati is generally a safe place to travel. However, it may be risky to be outside after dark in Beito or along the beach in South Tarawa, especially for single females. However, virtually all problems are caused by drunk males, not career criminals.
Normal common sense applies when moving around.
Some care should be taken on the roads as the traffic can include pigs, children, dogs and buses all fighting for road space.
English is the offical language of Kiribati along with the native I-Kiribati. While English is used heavily in South Tarawa the further away from the capital you go the stronger the I-Kiribati tongue. Most people on Kiritimati Island have some English. Nearly all Kiribatians also speak the local language Gilbertese, derived from the name of the Gilbert Islands named after Thomas Gilbert, the first European to discover the islands.
