Not far away from the capital Sarajevo, there is a Spring of Bosnia river. Getting there is a bit challengong, but walking distance is not more than 1h 30 min – slower walking tour.
When I was there back in 2009, there was no charge to get in. But later in 2015 they started to charge the entrance which is not more than 3 EUR.
Vrelo Bosnia is a good picnic place. Meadow all around the quiet river and it’s lakes, green eye resting views and some small small restaurants and ice cream sellers.
A Roman Bridge is located not far from Vrelo Bosne on the Bosna river in the Ilidža municipality, which was built in 16th century from original Roman stones and ruins of the bridge that stood there during the Roman period used to connect the Romans with the village of Aquae Sulphurae at the time. Ilidža is also known to have been an archaeological site dating 2400–2000 BC.
But I prefer this cute bridge made of wood. Romantic and peaceful.
The spring water at Vrelo Bosne is drinkable, however not recommended. It is not prohibited to take a bath, but water is cold and unpleasant.
