Tobia is small enough that getting around is largely not a concern. The village centre, the adventure camps and the river access points are all within walking distance of each other, and if you have arrived on an operator's shuttle you will be transported directly between the lodge, the put-in point and any other activity locations on the itinerary.
Visitors who have arrived independently and are not on a guided package will find the area easy to navigate on foot. The main road through the village passes the key operators, and local mototaxis are available for the slightly longer runs between camps if needed. There are no formal public transport options within the village itself.
The practical reality is that most people who come to Tobia spend their entire visit within a kilometre or two of the river. The destination is compact by design — it is a place where the activity is the point, and the geography arranges itself accordingly.
