Air transfers from Vancouver are accomplished via Pacific Coastal Airlines.
Tweedsmuir (Bella Coola, QBC)
Nimmo Bay (Port Hardy, YZT)

Two flights a day most of the summer, one flight daily otherwise

There is a 45-minute drive to Tweedsmuir from Bella Coola, the resort will meet your flight to do the transfer.

A helicopter or floatplane waits for you at the Port Hardy Airport to fly to Nimmo Bay. This flight is 20 minutes and is included in packages.

There are no roads to Nimmo Bay so I'll need to arrange helicopter transfer From Tweedsmuir.
