Swim
Restaurant Slap (Waterfall) lies next to a small barrage in the Vrbas and it is excellent swimming there on hot summer days when the water is not too high.
Join the locals in many small pools of hot springs just next to the river in Srpske toplice. It's free so don't expect it to be super tidy. You can buy beer and fruits there. It's an hour walk from town (walk on the right/southern river bed). There's also a bus stop. Just behind the springs starts a marked serpentine hiking path up to Banj Brdo (completely in the cool forest).
Spomenik na Šehitlucima
A very large WWII monument sitting on top of a hill south of town.

Ferhat-pašina džamija
This example of Islamic 16th century architecture was built during the time of the Ottoman rule. Built in 1579 it has a central fountain called Shaderwan, stone and iron fence. It is built in the classical Ottoman style. Ferhadija was listed as a cultural heritage of Bosnia and Herzegovina in 1950. Later it was protected by UNESCO until destroyed in 1993. The site and the remains of the mosque today are a national monument of Bosnia and Herzegovina, and the mosque is under reconstruction.
