If you are travelling by plane, it is easist to come through the airports at Dubrovnik or Split. By ship it is safe to come through Italy. Whoever travels by coach or car can do so along the Adriatic coast as far as Split and then make the turn for Medjugorje. From the south the road for Medjugorje is through Dubrovnik. Medjugorje and its surroundings are completely safe as far as residence is concerned.
Life goes on as normal.
However those who wish to go further into central Bosnia do so at their own risk.
