Dove Rosario twice on 2 Aug, both at low tide. Visibility on both dives was about 5’. We went around Urchin Rock on both dives. Tons and tons of different kinds of algae along with seaweed. There were spots 3’ deep. Never saw any oto but there was plenty of proof that they were there. Lost of sea cucumbers and yellow rock fish. Easy entry but the climb up to car required a break before the hill. Got a refill of air in Anacortes...and did two more on Sunday. Not much changed from the 2nd.
We dove Rosario twice this weekend, both at low tide. Visibility on the first dive was about 5 ft, 2nd dive was 15 feet. Best to dive at slack before an ebb for visibility, I have heard. Around Urchin Rocks (right entry mentioned on this site) it is fairly protected. Amazing amounts of many kinds of algae.
This is a great dive site, except for the hike. There is plenty of sea life and a fairly large octopus at 35’. Vis was about 20’.
Cool place, but a pain to get all your equipment to the dive site. We brought an equipment cart, and it was still a long haul. But once you get out into the water, it is all worth it. Saw my first Wolf Eel! I hadn’t been diving in Washington before, so this was a good intro. I’m looking forward to going back for a longer dive vacation.
