The book "Bay Area Rock" lists this at 5.9. I'd have to agree. Good footwork eases the rating. It's a delightful route! Past the crux, there is a section so glassy that you can check your teeth for poppy seeds. While the top section eases up a lot, the view is great.
I just climbed this route today and its given a 5.10a rating in "Rock Climbing the Bay Area" and is a great little climb. First time up, a beginner like me had to use my arms a lot but was able to do it no problem and relaxed second time. Lots of fun and interesting rock.
