Mostar to Medjugorje

It's about one hour in each direction, so depending how much of the afternoon you have, it's possible. You could certainly visit the church, but whether there would be time to visit the apparition sites, I'm not too sure.

Thank you for the reply. How far is it from the town to the apparition site? I have been told by friends that it is a challenging hike. We are capable of the hike but may not have the time it requires. Thank you. Hank

It's an easy one-mile walk up to the apparition site. In September I imagine you'l have the place all to yourself ........ and about 1,500 Irish and Italian pilgrims.

You can take a taxi around Medjugorje for
about 5.00 €, say for to get to the foot of the Apparition Hill or to Cross Mountain, or back to the Church from these places if the weather turns rainy.
You need shoes with a good grip if going up Apparition Hill but it is not really that difficult.
Cross Mountain I understand is much steeper and I remember somebody saying that those solid walking sticks they sell in Medjugorje for 2 € were very useful in the climb. It also takes more time. Somebody else said that one would tend to climb Cross Mountain early in the morning before the temperature rises. A bottle of water is advisable.

The Euro currency is acceptable in Medjugorje, even though Bosnia is not part of the EU, and I imagine the Dollar would also be.

The Pansion Dubrovnik across the road from the Church and to the right has a restaurant.

The reason why Euros are widely accepted is that the Bosnian Mark is pegged to it, so local people know exactly how much a Euro is worth. Euros and Dollars float, so people don't know how much a dollar is worth without checking. That means that they are less likely to accept dollars.
