Lets put it simply - Algeria is not an easy place to get around. Public transport is hampered by poor infrastructure, roads are usually badly built and overcrowded, and traffic accidents kill a large number of people every year.
Let's get straight to the point - Algeria is a country wracked by terrorism. Terror groups have turned this North African nation into a hotbed of radicalism, providing a training ground for fundamentalists. However, the country does have tourism which makes this increasingly difficult.
Algeria is a tightly controlled country. Increased violence and civil unrest means police crackdowns are common. It's always a good idea to remain out of trouble at the best of times, but in Algeria, the need for personal vigilance is even more important.
Crime is a part of every country & shouldn't stop you seeing a destination. It's wise to know where the trouble is & avoid it. The crime rate in Algeria is moderately high & constantly increasing. Low standards of living mean more people are turning to criminal activity, watch your back in Algeria.
