There are considered to be 3 different dive sites at Madrona Point: "Big Wall", "Middle Wall" and "Small Wall". I always go out to the big wall, which is the biggest and deepest (90-100' deep at the base). That's where there are the wolfeels, octopus, lots of rockfish, sea whips and a few sponges (although most of them have been destroyed over the years). I've only been to the middle wall once and I wasn't impressed by the lack of fish and invertebrates. I've never been to the small wall since it's very shallow and I've found that the marine life in the Strait of Georgia is best below 60'. Despite my prejudice, I've heard from a few different divers that this small wall is actually pretty interesting and that there are lots of anemones and small things like nudibranchs. I finally dove here as a second dive-of-the-day on Feb. 19, 2017. You basically walk down to the beach and walk along the rocks as far as you can go to the left. There is a small canyon running down into the water at this point where you can enter the water easily.
I swam down the small canyon and turned around the corner, following the rocks on my right. The rocks became a wall bottoming out at about 20' deep. Visibility was 30-40'. I saw some plumose anemones in the distance and then soon the wall was covered with them. There were also patches of sponge that I don't remember seeing in these amounts anywhere else. On the sand at the base of the rocks there were some squid egg clusters. The wall gradually deepened to about 40-45' deep, where there was a plain of sand. I had sealions visit 3 different times on this dive. I swam back along the wall the same way I came.
