Leg Cove at the north-west end of Hanson Island is a good place to stay if you want quick access to moderate current through the Plumper Islands (3-4 knots max.) and to Weynton Passage (bigger current – check out Stubbs Island), the north western tip of Johnstone Strait and Blackfish Sound. The campsite itself doesn’t have a great view but the local area is a hot spot for wildlife: orcas, humpbacks, porpoises and sea lions.
If you’re looking for bigger current and bigger water, the Little Hanson campsite at the south-east end of Hanson Island puts you right near the pinch point of Blackney Passage. The current gets up near 6 knots at max with the associated whirlpools, boils, overfalls, etc. Not for the faint-hearted!
If you want more details, I’d be happy to do a Zoom call with you.
