Vrelo Bosne is a beautiful large quiet park surrounding natural water springs. In the center is a restaurant and playground. There are small bridges to cross and plenty of space for little ones to run around or take a horse and carriage ride along the tree lined road (approx 2miles).
Take the main road out of the city towards Mostar (Marsala Tita turning into Zmaja of Bosne, etc.). When you get closer to Ilidza (pass Radon Plaza hotel), keep going as if you were to go to Mo-star, but keep left on the ramp and go through the tunnel leading to Ilidza. After the tunnel, keep straight for a mile or so. Turn left at the intersection with a yellowish Orthodox church on the right hand side. The parking for Vrelo Bosne will be at the end of that road (half a mile or so). This will take you directly to the park.
