Mostar is an amazing town with great history. There is still a lot of damage from the war, which I think it interesting and thoughtful for older kids.
it makes you think, but is still fun, and not a downer. Two days is plenty, but there is a ton of stuff (castles, river rafting, swimming and waterfalls, hiking) in the area so Mostar would also make a wonderful base for a 3 - 7 day holiday. I loved the food, but it would be tough for a vegetarian.
Mostar was knocked to pieces in the ex-Yugoslavia wars of the 1990s and lost the famous graceful span of the Ottoman bridge, its key sight.
This has now been meticulously restored, as has the damage to the old town. There are a number of restaurants offering good views of the River Neretva gorge, lots of small craft shops and an unusual mixed skyline of minarets and church towers. Bosnia was pretty much off tourist maps for a long time but Mostar is perfectly safe, well worth a visit and easily accessed from Croatian resorts like Split and Dubrovnik.
Mostar is a compelling mixture of ancient and near history, of religions, of a city still dealing with the war of the 1990s.
It feels safe, and having coffee in one of the shops off the main tourist drag near Masala Square is a delightful way to watch the people. The gentleman who takes tickets in the Karadjo-bey mosque was particularly friendly and gave us insight into Bosnian life today.
It's a small town. There a many historical remains here such as the mosque during Turkish Ottaman empire and the old bridge.
In addition there is also many restaurants that serves tasty food.
