This another of the public rights-of-way along Tumbo Channel Road. A sign labels it as Beach Access 721, and it's just past house # 721. This access is the last one before East Point Park. According to the sidescan image and the marine chart, the topography seems similar to much of the rest of this coastline. I did a dive here as a second dive (after Salal Road) on Dec. 20, 2025. The trail was a reasonable length and steepness and it ended in a few steps and a small sandy beach.
I swam straight out from shore. Blocking my swim out were a series of very shallow (1-2' deep) rock ridges running parallel to the beach. At low tide, this would all be an exposed rocky shelf that you would have to walk over. Since it was a higher tide I had to crawl/drag myself over the rocks until it was deep enough to swim properly. After that it was still a surprisingly long swim to get below 20' deep. Maybe I swam out at a weird angle. Just like everywhere else in Tumbo Pass, the rocks were pretty bare above 30' deep. Visibility was maybe 15'.
Below 30' deep I started to see lots of red urchins and some California cucumbers. Below 50' deep, there were cup corals and nipple sponges. -Basically similar to the other Tumbo Pass sites, except here there seemed to be a bit less current-type invertebrates (even though I felt a surprisingly-strong current despite diving during a very low exchange). I looked around for basket stars, but so far I didn't see any.
I finally saw a basket star down around my maximum depth of just under 90' deep. It was the only one I saw on the entire dive. I assume I reached the end of the rocky area as shown on the sidescan image. I could see the rock dropping down about another 6' to a base of small boulders and rubble, but I couldn't see very far out past that with the darkness and limited visibility. The current was a bit strong for comfort and I was building up nitrogen since this was a second dive of the day, so I headed back to shore. Like the other Tumbo Pass sites, there were few fish here, but in one area I saw a few kelp greenlings and copper rockfish.
I usually rate these Tumbo Channel sites by the number of basket stars I see. This site only rates one star. The rocky area seemed pretty large though, so maybe there were more in areas I didn't visit. I might come back to have a second look, but considering the long ferry ride and the necessity of diving here on a good slack, it probably won't be anytime soon.
