Most of areas of the country, except some small sections, is quite safe, from military point of view. Nevertheless, the only area, which is recommended to be avoided, is western area at Rte Road, Xieng Khuang Province, where the military guards do not permit to enter to anybody who is not accompanied with military escort.
In east parts of the country, in direction to Vietnam border (especially in Hua Phan, Xieng Khuang, Sekong and Attapeu Provinces), extented terrain surface is full of non-activated mines and other military arsenal (UXO), which remained ther after 100 years of wars. Despite the fact that a risk of injuries is low for standard visitor, it is worth, to touch never any subjects, placed on the earth, where UXO could be found.
As far as robberies are concerned, so, this is not so big problem in Laos. Nevertheless, you are adviced to pay always an attention, and not to give a chance, with the imprudence, to pickpockets.
