Grendel’s Needle refers to a feature on a small island in San Francisco Bay. That feature is a slot in the rock on the westernmost of The Sisters Islands just off of Point San Pedro. When conditions are right it’s fun to paddle a kayak through the slot, an exercise we call threading Grendel’s Needle.
When we left our house in Albany, we had the windshield wipers going with dark clouds overhead. As we were crossing the Richmond-San Rafael Bridge though, we could see patches of blue sky and sun shining on San Rafael. Harbingers for a good day on the water.
Eight of us were on the water at 10:30, launching from the kayak ramp at the east end of the Loch Lomond Yacht Harbor. There was some discussion about whether wetsuits or drysuits would be the better option. For safety’s sake we like to “dress for immersion,” should we end up in the water. I opted for my drysuit. In hindsight the weather was quite mild and my wetsuit long john would have been more comfortable.



Once we were on the water we paddled out of the harbor and headed east rounding the Marin Islands. We then paddled on to Point San Pedro where we held up for some radio communications. We had a new member in our group who had never paddled through Grendel’s Needle, so we opted to head to The Sisters to thread the needle. With hardly any current going through the slot we had no trouble paddling back and forth through the slot. Trying to exercise some boat control I even paddled through the slot backwards.



After lunch at China Camp, we returned paddling close to shore. We were back at our launch site at about 2:30.



We logged 9 miles over the course of the day on relatively calm water. More photos are available in an online gallery.
