On our Class II trips, the Athabasca Mile 5 and the Athabasca Falls, we run two sizes of raft. One can fit up to 6-7 paddlers comfortably, and the other can fit up to 8-9 paddlers comfortably.
*Note: "Paddlers" do not include small children who will not be paddling, or our guides. Small children may sit in the middle or front of the raft, slightly increasing capacity. Additionally, total weight and balance are factors. Because of this variability, we do not guarantee raft sizes as it is up to the discretion of our guides to determine what is a **safe** raft size.*
As for our Sunwapta River trip, we only run one size of raft with oar frames. Because of this there is a strict maximum of 6 paddlers on the Sunwapta. This means groups of 7 or more will not be in the same raft. Another consideration on the Sunwapta River is the water level. In lower/higher water levels we may lower the maximum paddlers to 4 for safety reasons.
