Banja Luka, despite its first appearance, is an extremely safe city, both for locals and tourists. You have nothing to worry about if you use your common sense, and even if you don't, there is practically no chance something will happen to you. As soon as you stroll around the city, you will notice how friendly and kind locals are.
Just remember that there are still some unexploded land-mines in the fields in the whole country. So if you are trekking or hiking in the hills nearby, DO NOT go away from the marked pedestrian paths.
Kameni most (Камени мост) seen from the side of the Vrbas river.
Ex-Yu Rocks Festival This is the Woodstock of Banja Luka taking place on the banks of the beautiful Vrbas river at "Krupa na Vrbasu", about 4 km out of that town, 20 km south of BL. Strictly punk, rock and heavy metal bands, one can enjoy a possibly painful head-banging experience or just chill out at the festival's camp-site with a beer and a bonfire.
Climbing: 24km south of Banja Luka and 5km north of Krupa na Vrbasu is a nice climbing site; the 'stone bridge' (Kameni Most, Камени мост). More information you can for example get at "Extreme Banja Luka " climbing club.
Rafting: At Karanovac, 15 km south on the main road from Banja Luka is rafting club "Kanjon" from where you can go rafting in the Vrbas canyon . On the Vrbas, together with the Tara near Foča, the world championships of rafting were held in 2009.
Canyoning. Not far from Karanovac is the canyon of the Svrakava river, a small canyon where it is nice to try to climb through. Its a wild spot, it is not being commercially exploited. You can reach the canyon by going on the road towards Kneževo. After you pass the bridge over the Vrbas to Karanovac, there is a small road going on your left with an indication of Svrakava. That is just before the main road goes uphill into the forest. After that indication there are no others, so you'll have to find it from there on yourself. Its about 3 km further that road.(13.752222,100.493889)edit
If you really want to go canyoning, ask a local person to take you to Cvrcka canyon (Цврцка). Around 40 km south-east of town, between Kotor Varoš and Kneževo. On hot summer days you can track up to 18km through the canyon wading through the fresh water of the Cvrcka river. Not very difficult.
