Pros: Tight firm fairways, hold up well to moisture.
Cons: Not an easy course to walk.
One of the defining things about Granite Fields is how well it drains. If conditions have been extraordinarily wet to the point other courses are closed, cart path only, or walking only it is worth calling Granite Fields. There are places where the course will turn into mud but a good bit is just a very firm sand base that is basically impervious to water. For a crisp iron player, hitting off the firm sand base with a nice tight cushion of grass is just a real pleasure and treat here. Quite a few of the holes are interesting in terms of course management as well as being just visually attractive.
Another thing that makes Granite Fields stand out a bit is their greens, sometimes they putt slower than they chip and roll out. It can be easy to have a chip go 4 feet further than planned then come up 10 inches short on the putt when the putt is based off the roll out on the chip shot.
Originally the first hole was beside the club house and the 9th to 10th hole transition was out in the heart of the course. Since these nines have been swapped which means that walkers now need to walk from the clubhouse to the heart of the course to get to the 1st, then on the 9th walk back from the heart of the course to the clubhouse to get to the 10th. Even without that there are a few longish walks like between the 8th and 9th. The course is still walkable but not at all optimized for it.
The staff and owners have always been really friendly and accommodating, earlier this year a marshal brought out bottled water to our group as it was too early in the season for them to have bottled water on the course, which is their standard practice.
