Aleksa grew up around Banja Luka and still works on the river, the hills, and the small towns that sit a short drive from the city. Days with him usually mix a local guide, a driver, and the kit you need for the activity, whether that is a raft on the Vrbas, a traditional dayak boat through town, or a private walk into the caves and rainforest around Sipovo.
Most groups are collected from the city centre. The team keeps numbers small, includes the equipment unless a listing says otherwise, and will tell you the meeting point for that day rather than sending you to a single street address. Expect a straightforward, well-paced day with people who know the water, the roads, and where to eat afterwards.
