The Octopus Islands are very pretty, but we were there during a very gusty time... to be fair, it's always windy near Johnstone Strait. The wind travels over Quadra Island into all nearby anchorages.
We hardly slept last night because of 35-40 knots winds :/.
At low tide, as the water recedes, submerged rocks come out and create little lagoons, or bridges between islands.
