There is a remnant of a MacKenzie course there called Haggin Oaks...has one heck of golf shop too!
Noooooo to Haggin except for the golf shop and snack bar. You can see the original Mac plans for the course in the snackbar and alot of Sacramento golf history on the tables under glass but that is as close as you get. The course is horrible.
If you have private access, Granite Bay is probably the best in town, but the renovated Del Paso is also very good and will host a future senior open. I love Rancho Murieta North course, they have two, and a fly in small plane airport. They used to have a Senior Tour event there, figure eight layout with no parrallel holes, plenty of old oaks and rolling hills.
As far as the publics go, if you don't mind driving about 45 minutes north there is beautiful course at the Cache Creek indian casino called Yoche De He that sits back of the casino in quiet valley with no visable roads or houses.
Ancil Hoffman is a pretty parkland muni course that is next to the American River and usually a few degrees cooler and Mather is a former military course that is a muni now with plenty of trees and a rolling layout. Both are a bargain green fee wise.
Temperature is in the high 90's right now, but it's a dry heat.
If you need someone to play with on a weekend or holiday, shoot me a message.
