I Googled Bella Coola and offer this to you. Turn right when you come off the ferry. Drive up the road maybe 1/4 mile? There is a dirt road to the left. Goes up into the mountains. I am seeing clearings not far up the road. I'd scoot up there. Bella Coola is a small place, so, you don't go far to be away from buildings.
