Flight
There are two flights on each the Friday and Sunday. These are small planes so they might fill up quickly! The resort suggests coming on the earlier flight on Friday, and leaving on the earlier flight on Sunday (this is what we have booked ourselves). The flight is only 1 hour and according to a Pacific Coastal Pilot, is "the most beautiful route they fly". It may be a little turbulent- something to keep in mind.
Rental Car
The scenic drive to Firvale takes you across the Chilcotin Plateau before descending the "Hill" into the Bella Coola Valley. Head west from Williams Lake on Hwy 20, be aware there is a 80km stretch of dirt road that is well maintained and 4x4 is NOT necessary. You can check current road conditions on the Drive BC website. Another favourite is the Discovery Coast Loop, combining the ferry route and drive to create an epic road trip through British Columbia.
