Been playing Blue rock for almost a year now and my experiences have been nothing but positive.
The greens and fairways are better than most courses in the Bay Area.
Vallejo stays cool throughout the summer and that helps keep the grasses green and plush. The early Summer months will bring a little wind but nothing like the courses in Brentwood/Antioch area.
The amenities are fair, with a small cafe and separate golf shop. The only complaint I would have regarding this course is not having enough drinking fountains on the course and the cart girl doesn't come out before 9 or 10am.
The prices are outstanding for a course in this kind of condition.
I believe the weekend rates are $50 to ride and $35 to walk.
The west course is another great 18 hole treasure but I prefer the East.
